Motor buck starts cabinet XJ01-75KW auto decompression starter cabinet

JX01 auto decompression starter cabinet Uses: JX01 Series from lotus root decompression starter control box for AC voltage 380V, frequency 50HZ, power 11KW-500KW three-phase induction motor mouse as voltage starting and stopping use. Works with autotransformers depressurization, reduced voltage, output current is large to improve the impact of high current when the transmission network of the motor starter starter, and have the motor phase and overload protection. First, the starting performance counters from lotus root decompression starter motor when starting, starting current power line does not exceed 3 to 4 times the rated motor current, the maximum starting time of 2 minutes (including one sum or several consecutive weeks starting time) If the sum of 98 consecutive start time reached 200 minutes, the start of the cooling time should be less than four hours to start again, so this product for a long break starting purposes only, not suitable for use in the frequent operating conditions. Second, the product structure starting from lotus root decompression protective cabinet for the box-type structure, auto-transformers, AC contactors, intelligent digital motor protection (relay, time relay) and other components, for 75 kilowatts and below the product, Department of automatic control, 80 kilowatts or more products and, with manual or automatic control mode in the 0 to 240 seconds can be automatically adjusted to control the start time, auto-transformer switching equipment, intelligent digital motor protection by the switch There are 60% of rated voltage (65%) and 80% of the two groups of taps, the factory connected to the 60% (65%) taps, if the user needs to use a larger starting torque, 80% of which can be accessed on the tap, and overload, phase and voltage protection. Third, the technical specifications of a starter box and thermal motor protection relay current setting: 75KW and below, the protector of the tuning current is equal to or slightly greater than the rated current of the motor, but not more than 1.05 times the motor current setting. 2,115 KW or more, the current setting is equal to the rated current of the motor control box is multiplied by the current transformer ratio. Fourth, install and use (1), no more than 2000 meters above sea level; (2), ambient temperature is not higher than +40 ℃, not lower than -10 ℃; (3), air relative humidity less than 85%; ( 4), not more than 0.5 mm amplitude, frequency is not greater than 600 beats per minute vibration; (5), in the vertical gradient of not more than 5 degrees; (6), in the absence of explosive medium, and the medium enough to corrode metal and damage the insulation of gas and conductive dust. (7), the product wiring diagram in Figure 1, 2 and Table 3. (8) before installation to use, it is necessary to review the wiring according to the wiring diagram is correct, the actual starting time required to adjust the motor relay operating time, the rated operating current of the motor, adjust or thermal motor protection relay action current, then the test operation. Five automatic operation: on the power switch (80 kilowatts or more switches cabinet knife), the green indicator light, the rotary switch to "Auto" position (80 kW), press the start button, the motor begins to start, the green light is off, that is bright yellow, while the time relay to work, after a certain time (ie, time relay setting time) time relay contacts are closed, AC contactor is switched on, the motor is automatically switched to normal operation, while yellow The red light is off, press the "Stop" button, the motor stopped working. Manual operation (80 kW) knife switch is closed, the green indicator light will be installed for the switch to "manual" position, press the "start" button to start the motor starter, green light, yellow light that is bright, the motor speed to be close When synchronous speed, the ammeter pointer close to the rated motor current is gradually reduced, then "run" button, the motor started to work, while the yellow light goes out and the red light, press the "Stop" that the motor stopped working. Note 1: From the start switch to the operation must be carried out near the rated speed of the motor, otherwise easily damage the contacts, but also detrimental to the transmission grid. Note 2: During operation, if the motor protector, thermal relay action occurs, you should carefully check whether the motor overload, phase failure, in order to continue the work until after sending failure.
