Control various devices on and off. The composition of the main circuit breaker contacts or starter or electronic control panel, the control knob or handle and ancillary. Applications and is widely used. All walks of life. Switchgear is an electrical device, outside the master switch into the cabinet first, then enter the sub-control switch, each branch according to need. Such as instrumentation, automation, motor magnetic switch, all kinds of exchanges and contacts, and some also set up the high-pressure chamber and the low-voltage switchgear room with high-voltage bus, such as power plants, and some also have major facilities in order to protect low-cycle load shedding. common taxonomy editor in accordance with the voltage level of classification according to the voltage level of classification is usually referred to in this paragraph and the following AC1000V low-voltage switchgear (such as PGL, GGD, GCK, GBD, MNS, etc.), AC1000V above called High Voltage Switchgear (eg GG -1A, XGN15, KYN48, etc.), sometimes high-pressure cabinet voltage AC10kV called the MV cabinet (eg XGN15 10kV type RMU). In accordance with the voltage waveform classification is divided into: AC switchgear, DC switchgear according to internal structural classification withdrawable switchgear (low-voltage withdrawable switchgear, low-voltage switchgear fixed-separated, metal armored away switch cabinet, cabinet trolley) Use according to classification line counters, outlet cabinet, metering cabinets, counters compensation (capacitor banks), the corner cupboard, cabinet bus operation flow edit this section transmission operation first installed after the closure plate, and then shut the door before the next operating grounding switch spindle and so that opening by transfer vehicle (platform trucks) will handcart (is in the open state) into the cabinet (test position) of the second plug into the socket on the static (test position indicator light) (closed before the Gate) to the trolley with the handle from the test position (OPEN state) is pushed into the working position (working position indicator light, the test position indicator is off) switch on the circuit breaker outage (overhaul) operation circuit breaker points Handcart exit gate with the handle from the operating position (OPEN state) to test position (working position indicator is off, the test position indicator lit) Open the front door of the second plug socket pulled static (test position indicator is off) Used with a transfer vehicle will (is in the open state) to exit shaft grounding switch operation outside the cabinet and make it open the seal plate and closing the front lower door Note: arrester handcart and the (lower) PT trolley buses can run When pulled outside the cabinet directly relevant standard edit this section SJ / T 31401-1994 |.

Uses GGD AC low-voltage power distribution equipment for substations, power plants, industrial enterprises and other power users of AC 50Hz, rated working voltage 380V, rated operating current distribution system 1000-3150A as power, lighting and power distribution equipment issued power conversion, distribution and control purposes. GGD AC low-voltage distribution cabinet is based on the requirements of the Department of Energy, the majority of electricity users and design department, according to the security, economic, reasonable and reliable design principles of new low-voltage power distribution equipment. products high breaking capacity, dynamic thermal stability, electrical program flexible combination of convenience, family, practical, novel structure, high level of protection can be used as low-voltage switchgear equipment replacement product. Model and meaning structural characteristics ■ GGD AC low-voltage distribution cabinet cabinet cabinet to adopt a common form of cold-formed steel frame with 8MF local welding assembled, and there are mounting holes 20 die, common factor is high. ■ GGD cabinet full account of the heat. In the cabinet By varying the number of upper and lower ends of body heat Slots, when the electrical components inside the heat, the heat rising through the top slot discharge, and the cold wind constantly added into the cabinet from the bottom of the slot, since the sealing of the cabinet and formed a natural ventilation path to achieve the purpose of cooling. ■ GGD cabinet in accordance with modern industrial product design requirements, using the golden ratio designed cabinet shape and size of each part of the split, so that the entire cabinet nice, new look. ■ cabinet cover can be removed when needed, easy to assemble and adjust the site of the main bus, Roof corners with rings for lifting and loading. ■ cabinet protection rating of IP30, users can according to environmental requirements Choose between IP20-IP40 Model and meaning GCK series G is enclosed switchgear;. C is out of style; K is the motor control center. GCK Low-voltage withdrawable switchgear (hereinafter referred to as switch cabinet) consists of two parts, power distribution center (PC) cabinet and motor control center (MCC). The device is suitable for AC 50 (60) HZ, rated working voltage is less than equal to 660V, rated current 4000A and below the control and distribution system, as power distribution, motor control and lighting distribution equipment. GCK switch cabinet meet IEC60439-1 "Low-voltage switchgear and control equipment", GB7251.1-1997 "Low-voltage switchgear and control equipment ", GB / T14048.1-93" low-voltage switchgear and control equipment General "and other standards. Switching Talent Network has mentioned such production standards and has a high breaking capacity, dynamic thermal stability, advanced and reasonable structure, flexible electric scheme, series resistance, versatility, any combination of program modules, one cabinet. Loop accommodated more, save floor space, high level of protection, safe, reliable, easy to maintain advantage. Structural features 1, the entire cabinet with the assemblage structure, modulus Hole, parts versatility, applicability, high degree of standardization 2, upper cabinets to bus room, electrical room to the front, the rear is cable into the outlet chamber, among the chambers have steel or insulating panels for isolation, to ensure safety. 3, MCC cabinet drawer compartment door with operating handle circuit breaker or disconnecting switch of a mechanical interlock, only when the door handle breaking position 4 can be opened, the power switch, contact switch and MCC cabinet drawer has three positions:... the on position, the test position, the open position of the top 5. The switchgear according to need can be installed by the electrical bus bridge ③GCS series: Model and meaning use GCS Low-voltage withdrawable switchgear used in the three-phase AC frequency of 50Hz, rated working voltage of 400V (690V), rated current 4000A and below the hair, as a power supply system, power distribution and motor centralized control, capacitor compensation. widely used in power plants, petroleum, chemical, metallurgy, textile, high-rise buildings and other places, can also be used in highly automated large-scale power plants, petrochemical systems, require places with computer interface.
