Chint NH40 dual power automatic transfer switch NH40-100 / 4SZ Chint NH40 dual power automatic transfer switch NH40-100 / 4SZ Chint NH40 dual power automatic transfer switch NH40-100 / 4SZ dual power means: one controlled by a microprocessor with in electrical power systems and grid electricity network or grid electricity and generator power starter switch enables continuous source of power supply. The basic role of PC-class dual power: Only complete dual power automatic transfer function, do not have short-circuit breaking current (only access, load) functions; CB-level dual power: both complete dual power automatic transfer function, but also has a short-circuit current protection (can be switched on and breaking) function. Edit this paragraph, also known as a basic introduction to ATS ATSE, is Automatic transfer Switching equipment abbreviation definitions 1.ATSE 1.1 dual power switch appliances (switch) Transfer Switching Device (Transfer Switch) one or several load circuit from a power conversion to another electrical power. 1.2 Automatic Transfer Switching Equipment (ATSE) Automatic Transfer Switching Equipment (ATSE) by one (or several) switch electrical appliances and other electrical components necessary for monitoring the power supply circuit, and one or several load circuit from a power supply automatically conversion to another electrical power. Electrical industry referred to as "dual power automatic transfer switch" or "dual power switch." GB standard definition of ATS products by one (or several) switch electrical appliances and other electrical components necessary for detecting the power circuit, and one or more of the load circuit automatically switch from one power to another electrical power. ATS and UPS, EPS in the name of the relatively confusing. Emergency Power Supply EPS is the abbreviation, the Chinese called the emergency power supply. UPS Uninterruptible Power Supply is the abbreviation, the Chinese called uninterruptible power supply. ATS (ATS) Automatic Transfer Switching Equipment is the abbreviation, the Chinese called the automatic transfer switching equipment. ATS suitable for key areas such as building fire load of dual power supply, EPS EPS is suitable for solving the emergency lighting, emergency lighting, fire fighting facilities, a load of power supply equipment for the main goal, to provide an independent compliance with fire codes emergency power system circuit. UPS is to provide electricity for the IT industry equipment, providing pure, uninterrupted backup power. Diesel generator power supply suitable for the need to place a long time back-up power supply and ATS, EPS, UPS used in conjunction. Practice 1, when a power outage for any reason, and in a relatively short time when the power supply can not be restored, you must enable standby power. Steps: ① cut electricity supply each breaker (including power distribution control room of each circuit breaker cabinet, dual power switching power supply circuit breaker box City), anti-pull double-throw switch to send down the side of self-powered, maintain dual power switch box-owned electricity supply breaker in the OFF state. ② start when backup power (diesel generators), standby group is operating normally, the sequence generator breaker is closed, self-powered control cabinet each breaker. ③ closed one by one inside each backup power supply switching circuit breakers, each load transmission. ④ standby power during operation, the operator on duty shall not leave the generator, and adjust the voltage, frequency and other plant based on load changes, abnormal timely manner. 2, when the mains power is restored, the power conversion work in a timely manner should be cut off standby power, restore electricity supply. Steps: ① order individually owned disconnect power to each circuit breaker, the order is: dual power switching power supply circuit breaker box → self-owned power distribution cabinets each circuit breaker switch → → generator always double throw switch to City electricity supply side. ② Press diesel engine shutdown step down. ③ in order, from the mains power supply to the main switch is closed each one by each branch circuit breaker switch, dual power switching box since the mains supply breaker to the closed position. 3, check the meter and LED indicates whether the normal startup transformer cooling fan. The basic classification dual power automatic transfer switch (hereinafter referred to as dual power) is the use of molded case circuit breakers and load switches are two major types of the following two kinds of products to be introduced Edit this paragraph the main goods produced CB-level dual power automatic transfer switching equipment is YQJJ2-63H HYCQ5 series derived from the terminal-type automatic switching device, suitable for AC 50Hz, rated working voltage AC400V / 230V, rated current up to 63A three-phase four-wire (also available for one-phase line) of dual power grid, automatic one or several load circuit from a power supply connected to another power source, in order to ensure the normal power supply load circuit. This product is suitable for industrial, commercial, commercial and residential floor and other more important places. Structure YQJJ2-63H automatic transfer switching equipment by miniature circuit breakers (DZ47-63) stand-alone operating mechanism, the control loop, etc., all the components installed on the same floor. Automatic transfer switch electrical control supply voltage AC230V, mechanical life of 5000 times. Performance YQJJ2-63H dual power (only available automatic recovery) for two-way power (commonly referred to as power and standby power) phase voltage (automatic control power) simultaneously detect when normal power supply is abnormal, that miniature circuit breakers The A-phase or phase loss of pressure occurs, the automatic control without delay to enable the device to switch to a backup power supply; when the normal power supply back to normal, automatic control to enable the device to return without delay to the common power supply is not allowed simultaneous two-way power anomalies. Performance description Powerful> automatic recovery> Self vote of no self-recovery / mutual backup> Self pitcher complex> manually operated controller functions> A type (built-in): Mains - Mains conversion fire linkage optional> B type (external): Mains - Mains electricity conversion - Convert generator load unload communication options complete solution> standard configuration model, custom configuration model> according to IEC and GB standard> through the CCC certification and EMC test Rated voltage: 690V Rated current: 1A-3200A Poles: 4P Mechanical life: 8000 Minimum switching time: 1.5s good installation performance features ■ ■ double row composite contacts, cross-pull mechanism, micro-motors pre-storage and micro-electronic control technology, the basic realization of zero arcing (no arc chute) ■ using reliable mechanical interlock and electrical interlock ■ adopt zero-bit technology, emergency situations can be forced to zero (and cut off two-way power) ■ with isolation function, to achieve reliable power supply and the load between the obvious-off position indicator, padlock and so on. ■ high reliability and service life of more than 8000 times ■ mechatronics design, switching accurate, flexible, smooth ■ electromagnetic compatibility, anti-interference ability, without external interference ■ ■ high degree of automation switch has multiple input / output interface easy remote control and system automation PLC ■ switching without any external control components ■ appearance, small size, light weight, by the logic control board, with different logic to manage directly mounted on the motor switch inside the gearbox operation to ensure that the operation of the position switch. Describes the application of the relevant range of industrial fields, energy, infrastructure, data centers, public buildings, areas, residential ● ○ ambient air temperature ambient air temperature limit + 40 ℃; ○ ambient air temperature limit -5 ℃; ○ ambient air temperature for 24h average does not exceed + 35 ℃. ● elevation: the installation site altitude does not exceed 2000m. ● atmospheric conditions: air relative humidity in the ambient air temperature is + 40 ℃ does not exceed 50%; at the bottom than the temperatures can have a higher relative humidity; the wettest month of the monthly average maximum relative humidity of 90%, while the month The monthly average minimum temperature of + 25 ℃, and taking into account the temperature changes on the surface of condensation.
