PSW200 type Ring Main Unit boundary switch controller 

Summary

According to integrated domestic and foreign advanced technology, the actual demand of the power distribution area, PSW200 Ring Main Unit boundary switch controller is the latest development of the company's new generation watchdog controller. The equipment is installed on the responsibility boundary point of 10kV overhead distribution line, which can achieve to automatically remove single phase to earth fault and isolate phase short circuit fault.

Ring Main Unit boundary switch controller is designed for demarcation of the switch body intelligent control to protect the control function and communication function, controller and  switch body through the control cable and the aviation connector are electrically connected to achieve the protection and automatic monitoring function. The product is widely used in urban and rural 10kV overhead distribution line.

Product features

· Device using zero sequence power direction criterion, can accurately judge the single-phase grounding fault inside and outside the world.

· The device can be applied to the ground system of neutral point, small resistance grounding and arc suppression coil grounding system.

· Device resistor divider voltage sensor or voltage transformer, the internal circuit and voltage signal isolation device.

· The device can be used to shield the electromagnetic interference and improve the stability of the product.

· With battery management function. To prevent battery over charge, over discharge, improve battery life.

· Controller with data communication function can be achieved the background of data exchange through the GPRS data communication module.

Main functions

· Measurement function: three-phase voltage, current, zero sequence voltage, current, 16-48 remote signaling, 26 remote signaling.

· Protection function: single phase earth protection: interphase short circuit protection ,over current protection, over and under voltage protection,acceleration reclosure brake.

· Automation function: reclosing, incident record, communication.

PSW200 boundary switch controller unit is composed of a 128*64 graphics dot matrix liquid crystal, 10 indicators and 5 buttons:


The status indicator is made up of 10 indicator lights, each of which is as follows: 

Indicating lamp

Function

Power Supply

After the device is powered on, the power lamp is always on.

Operation

After electrify self-checking of device is normal, the operating lamp flashes

Close position

After close position input signal high-level input, "Close" indicating lamp is always on

Open position

After open position input signal high-level input, "Open" indicating lamp is always on

Energy storage

After energy storage input signal high-level input, the "Energy storage" indicating lamp is always on.

Over current alarm

When short-circuit fault signal is detected, the "over current alarm" indicating lamp is turned on.

Grounding alarm

When earth fault signal is detected, the “grounding alarm“ indicating lamp is turned on.

Protective release

When controller makes tripping action, the "protective release" indicating lamp is turned on.

Air pressure warning

After air pressure warning input signal high-level input, the "air pressure warning" indicating lamp is always on.

Voltage alarm

When under-voltage, over-voltage fault alarm, the "voltage alarm" indicating lamp is turned on.

Keyboard is composed of 5 keys, the key functions are as follows:
