Bw-ljp intelligent power screen is our company according to the market and customer needs to develop products. The product is suitable for the intelligent distribution system of substation, power plant, etc., to provide reliable and stable AC power supply.

Conditions of use

● Ambient temperature: -10℃~40℃

● Altitude: Altitude can be customized according to customer requirements

● Air humidity: not more than 50% at +40℃, higher humidity is allowed at lower temperature, not more than 90% at +20℃

● Installation inclination: the difference with the plumb line is not more than 5°

● Installation site mechanical vibration amplitude is not more than 0.05mm, frequency is not more than 600 times/min

● The surrounding medium has no explosion danger, no conductive dust and corrosive gas

 

Technical characteristics
● BW-LJP intelligent electric screen components in accordance with customer requirements production.

● AC circuit leakage protection switch, to ensure the safety of operators.

● There is an indicator light in the output loop to monitor the status of each switch.

● Incoming loop, automatic double power supply device, main power supply (I) power failure, standby power supply (II) should be automatically input, to ensure uninterrupted power supply. The switch can be set to "manual" and "automatic" position by changing the handle, which is convenient for personnel to control.

● The whole system adopts intelligent automation control, through PLC, time collection of circuit breaker switch "on", "off" state and fault node, by THE PLC LCD screen display the two states, when any feeder fault trip, can view the fault loop and fault time through the PLC LCD screen. Through RS485 communication, switch status and fault remote transmission, RS485 communication adopts MODBUS communication protocol.

● The system through 1PV, 2PV intelligent digital display meter, time measurement of input line power and other parameters, parameters can be transmitted through RS485; System through 1PM, 2PM intelligent digital display meter, always measure the N loop current, parameters can be transmitted through RS485.
