Abstract
A high voltage power electronic isolating switch that can be closed and opened automatically or by remote control, which comprises a electronic PT for monitoring operation power source, a direct- current system, a computer controller that can receive signals, a high voltage part formed by the electromagnetic mechanism and the contact system as well as a remote-control emitter directly operated by the working personnel; and is also equipped with a close resisting device with functions of preventing the isolating switch disconnecting with load and mistake close of the switch. The electromagnetic valve is controlled by the controller and drives the movable contact of the isolating switch to move, so the open and close functions are realized; the controller also controls the locking mechanism for preventing the mistake switching-on and switching-off with load, the high work reliability is guaranteed. Under the situation of power-cut or equipment failure, the detachable type manual on-off device is available, which can be operated by manpower.
Description
Affiliated technical field
The utility model relates to the isolation switch device of electric power distribution network make and break in a kind of electric power system, but particularly a kind of under high voltage the distant place control or the isolation switch device of make and break automatically, be applicable to mainly and will load in the power distribution network of 10KV and following electric pressure and power supply is switched on or switched off isolation infalliblely that obvious visible fracture is arranged under the disjunction state.
Background technology
As is well known, in distribution network, for install, maintenance and troubleshooting, isolating switch is must obligato important power consumption equipment.Line disconnecting switch in the past is also simple, low price, but with low content of technology, function is extremely limited, must pedal bar during operation, hand-held insulating rod, by carrying out the make and break operation mutually, very inconvenient, also dangerous, interruption duration is long, loss of outage is big; In addition, operation also is subjected to the weather conditions considerable restraint, more can not control automatically or long-distance remote control, and distribution network automated development can not satisfactorily be realized.
Summary of the invention
In order to overcome the heavy and unsafe manual operation that has the existence of high voltage network isolating switch now and itself can't to realize the shortcoming of automation, the purpose of this utility model is: creatively application of electronic technology is arrived field of electrical equipment, provide a kind of function outstanding atypical brand-new isolating switch.This type isolating switch straighforward operation contactlessly or operation automatically, safe and reliable.
The technical scheme of this type isolating switch is: the moving contact of this type isolating switch directly drives by the electromagnetism valve actuation is unshakable in one's determination.Electromagnetically operated valve solenoid power supply is made of high-voltage electron, direct current system and contactless control switch.Direct current system is made up of rectification circuit and storage capacitor.The noncontacting switch of the various motions of control electromagnetically operated valve is controlled by controller.Controller is made up of signal reception shaping circuit, computer decoding, drive circuit again.For minification, reduce electromagnetically operated valve and close a floodgate and switching winding, adds a middle transition coil that joins with switching winding and closing coil string (also) again by kenotron.The whole members of this type high voltage isolator all are in high potential.For simplifying member, this type isolating switch is that phase-splitting independently is provided with, and interchangeability is strong, but the three-phase same period or phase-splitting operation.The safety of using for guaranteeing also is provided with the operate a switch resistance of function and anti-error closing of anti-on-load and closes device.For preventing fault under this type isolating switch parts deadly condition, also be provided with split type manual breaker in addition.
The invention has the beneficial effects as follows and saved complex mechanical construction, realized the electronic type structure of high voltage isolator.Can be easily automatically or the remote control security operation, quick action has increased the action frequency (life-span) of isolating switch greatly, has increased function, makes the isolating switch technical merit improve a new level.
