Currently, the secondary control circuit of permanent magnet vacuum high-voltage switch gear just develops towards diversified direction.Numerous research promotees
Into the continuous improvement of permanent magnet vacuum high-voltage switch gear secondary control technology.But current permanent magnet vacuum high-voltage switch gear is secondary
Control loop is although more advanced, but its manufacturing process and assembly technology are more complicated.
Currently, ZK is breaker, CZ1 and CZ2 to the secondary control loop of permanent magnet vacuum high-voltage switch gear in figure as shown in Figure 1:
For power contact；QF is the switch contact to link with the actuating mechanism of permanent magnet vacuum high-voltage switch gear, action process are as follows: permanent magnetism is true
The actuating mechanism closure (i.e. permanent magnet vacuum high-voltage switch gear closes a floodgate) that outage compresses switch, then QF is disconnected, permanent magnet vacuum high-voltage switch gear
Actuating mechanism disconnects (i.e. permanent magnet vacuum high-voltage switch gear disconnects), then QF is closed；HC is that the combined floodgate of permanent magnet vacuum high-voltage switch gear contacts
Device coil, HC1 and HC2 are the closing contactor contact of permanent magnet vacuum high-voltage switch gear；HQ is the combined floodgate of permanent magnet vacuum high-voltage switch gear
Coil.When permanent magnet vacuum high-voltage switch gear disconnects, QF is closed at this time, and CZ1 and CZ2 are not powered on；At this point, when being closed ZK, this
When CZ1 and CZ2 connect with power supply signal+HM ,-HM, closing contactor coil HC is powered at this time, at this time closing contactor contact
HC1 and HC2 are closed, and closing coil HQ is powered at this time, at this time the actuating mechanism closure of permanent magnet vacuum high-voltage switch gear, permanent magnet vacuum
High-voltage switch gear closes a floodgate；While permanent magnet vacuum high-voltage switch gear closes a floodgate, QF is disconnected, and HC is powered off at this time, and HC1 and HC2 are disconnected, and is closed a floodgate
Coil blackout, so as to complete a making process of permanent magnet vacuum high-voltage switch gear.
Currently, permanent magnet vacuum high-voltage switch gear close a floodgate when, due to permanent magnet mechanism close a floodgate when need king-sized electric current ability
It is enough to close a floodgate, so contactor control power supply is widely used in its secondary control loop.But using control loop as shown in Figure 1
When, once contacts of contactor is burnt, it is not only unable to complete closing operation, and easily burn actuator coil, not only wastes material,
It is also possible to leading to the generation or further expansion of failure；Simultaneously as starting current is larger, so that the control loop of Fig. 1 exists
In actual work, the contact of contactor generates adhesion, so that HQ is persistently powered on and burnt；In addition, the control loop of Fig. 1 exists
In actual work, since electric current is larger, electric arc can be often generated during startup, so that the safety of circuit is seriously affected,
Limit the applicable situation (for example coal mine etc. requires Arc-free application) of control circuit.
