Embodiment Construction

[0019] The invention belongs to a remote control method for an isolating switch motor power supply. The method is as follows:

[0020] The wiring diagram of the electric operating mechanism of the isolating switch consists of relays KM1-KM3, intermediate relay K4, remote / local transfer switch (operating handle) QC, motor power supply air switch QF1, control power supply air switch QF2, overload protector GDH, travel switch SL1 -SL3 and other components.

[0021] Adopt two new ABB company models AS09-30-10-25 as the relay KM3 and ABB company model CR-MX230AC2 intermediate relay K4: KM3 and K4 both contain a set of coils (KM3-A1 and KM3-A2, K4- A1 and K4-A2), where KM3 also contains 3 sets of normally open main contacts (a set of KM3-1 and KM3-2, a set of KM3-3 and KM3-4, a set of KM3-5 and KM3-6), 1 set of normally open auxiliary contacts (KM3-13 and KM3-14), 1 set of normally closed auxiliary contacts (KM3-(-1) and KM3-(-2)); K4 contains 1 set of normally closed auxiliary con...

Abstract

The invention relates to a remote control method for an isolated switch motor power supply. Two sets of relays are used to transform a substation secondary circuit, a motor power supply remote controlcircuit is installed in an isolation switch mechanism box, an isolating switch motor circuit and an isolating switch control circuit are improved, through secondary cable modification, the circuit and the modified circuit are connected to corresponding measuring and controlling device remote control circuits via a circuit breaker terminal box and a junction control box, and the remote control ofa dispatching console for the substation isolated switch motor power supply is achieved.

Description

technical field [0001] The invention belongs to the application field of electrical equipment automation technology, and is especially suitable for the integrated regulation or program control of primary equipment in unattended substations. Background technique [0002] With the continuous expansion of the grid scale and the complexity of the grid structure, the error rate of substation switching operations is getting higher and higher due to its complicated process. With the development of the intelligent technology level of the power grid, the requirements for the level of intelligence and security of the power grid are getting higher and higher. The dispatcher and the monitor of the traditional power grid dispatching automation system are separated. , the smart grid regulation and control integrated system is a system that integrates dispatching and control, and achieves the integrated mode of "scheduling + control". It has high-reliability redundancy and supports multi-...
