The method and its relay power control module of A.C. point machine phase failure protector relay power supply.
Background technique
Rail track changes the operating path of train by track switch, and the equipment for changing switch location is known as goat, according to
The difference of action power, is divided into DC electric switch machine and A.C. point machine, and A.C. point machine uses three-phase alternating current
Motor, when three-phase alternating-current supply breaks phase, the electric current of another two-phase increases sharply, and causes threephase motor winding due to temperature rise
It is high and be burned out, therefore in A.C. point machine track switch actuating circuit, be provided with phase failure relay, when disconnected phase occurs
When, protective relay control circuit cuts off the action power of goat by the control to protective relay in time, to protect three
Phase motor is from damage.
Currently, the phase failure protector used on railway, protective relay control circuit power supply mode mainly has three categories:
1. taking electricity from three-phase alternating current operating current using three current transformers, three transformer secondary series connection pass through electric current
Turn potential circuit, generate three voltages, then by these three voltages after vector superposed, a voltage is generated, after rectified filtering
Directly driving picks up protective relay；
2. taking electricity from three-phase alternating current operating current using one or more current transformers, supplied after rectified for control unit

Cross transformer and take electricity from the voltage of any two-phase of 380V three-phase alternating-current supply), power supply mode only has one kind, single way to take power
Poor anti jamming capability and lead to poor reliability, when its power supply module is out of order, whole system can be made to fail, phase failure protector is not
It can work；
2. taking the power supply mode of electricity for electric current, there is also following deficiencies:
(1) when there is high current due to load overload, power supply short circuit etc., high current will cause the primary side of current transformer
It overloads and occurs；
(2) when goat stops working, whole system can power loss；
3. taking the power supply mode of electricity for voltage, there is also following deficiencies:
(1) when there is big voltage due to voltage raising or thunder and lightning, voltage will be caused to take a side overvoltage of the transformer of electricity
And it breaks down；
(2) since power transformer is connected with 380V three-phase alternating current working power for a long time, the external causes such as thunder and lightning are intersected by 380V tri-
When power supply module is damaged in galvanic electricity source, whole system can be made to fail, phase failure protector cannot work.
