Description

A kind of disconnecting switch

Technical field

The utility model is related to disconnecting switch, specially a kind of to be main type of drive with gear connecting rod rotation and be enclosed in Disconnecting switch in crossbeam.

Background technology

Existing high voltage isolator is with the rod-shaped connecting rod and abnormity of a series of complex such as connecting rod, connecting lever, eccentric wheel, pull rod Connecting lever realizes disconnecting switch breaking-closing operating lever principle in a manner of promotion；

It needs to be connected one by one and adjust repeatedly when existing disconnecting switch installation, and operation stability and reliability are poor, Operation each time be required for manually arriving site inspection whether divide-shut brake in place；

Since the high voltage isolator overwhelming majority is for open air, the transmission such as existing disconnecting switch its connecting rod, lever and even The exposed of relay part is very easy to get rusty and corrode and rotary part bite；

Existing disconnecting switch determines the angles and positions of current-carrying part with mechanical position limitation, is locked using the support of connecting rod Determine opening and closing state；

Existing high voltage isolator is all made of auxiliary switch or travel switch to control motor start and stop, add mechanical position limitation Come complete disconnecting switch divide-shut brake action and positioning operating mechanism, and divide-shut brake in place when cannot be detached from running part, it is complete Full reliability and accuracy dependent on operating mechanism and secondary component.

Existing disconnecting switch disadvantage is as follows：

1., it is complicated, with lever connecting lever push be major way be driven：Existing disconnecting switch is with connecting rod, connecting lever, bias The rod-shaped connecting rod of a series of complex such as wheel, pull rod and special-shaped connecting lever realize disconnecting switch lever principle in a manner of promotion Breaking-closing operating；

2., great number of driving accessory it is in bulk, need Assembling, installation and debugging heavy workload and technology require high：Due to existing The supply in bulk of some a large amount of accessories of disconnecting switch, needs Assembling and debugging, as many as link to cause installation difficulty big, to assembly Work technical ability and sense of responsibility are more demanding；

3., the exposed installation of transmission parts, it is affected by environment larger, need periodical power failure examination and maintenance, maintenance cost is high： Since the disconnecting switch overwhelming majority is run outdoors, the transmission parts of existing disconnecting switch are entirely exposed installation, and even Socket part position is huge more, is easy corrosion phenomenon occurred by such environmental effects, occur mechanical card resistance phenomenon cause divide-shut brake less than Position, power failure examination and maintenance each time will all bring huge cost to waste；

4., there is no on/off switch self-sustaining structure, and cutter head cannot be detached from operating mechanism power source afterwards in place；Existing isolation Switch is all made of connecting rod and connecting lever and forms positioning support locking with limited block, stops by the travel switch of operating mechanism itself dynamic Power exports, it is easy to because loosening for some transmission parts causes running contact to detach or closed a floodgate with travel switch failure Phenomenon is burnt in punching generation on-load arcing, and great security risk is brought to operation of power networks；

5., operating mechanism it is complicated, depend on the reliability of electric control system, need professional person to adjust operating mechanism With the accurate fit of cutter head：Existing disconnecting switch utilizes the electrical controls member device such as travel switch using operating mechanism as core component Part start and stop motor realizes the control of divide-shut brake stroke in conjunction with limited block, needs the work angle of operating mechanism and cutter head tune It is whole to arrive unanimously, highly dependent upon the reliability of electric control system, the operation risk of electric control system is superimposed on primary conductive Part；

6., exposed critical component, environmental suitability is poor, high to installation foundation stability requirement：Existing disconnecting switch makes Spread all over various climatic environments outdoors with most of, exposed component gets rusty easily corrosion etc., due to the phase interaction of interphase connecting rod It is uniformly controlled with mechanism case, any deformation of installation foundation and the deformation of component materials will all influence the normal fortune of cutter head Row, brings serious security risk；

For these reasons, there is an urgent need to invent a kind of simple for structure, factory's pre-debug complete scene may be implemented blind dress, In the way of replacing lever pushing in a manner of gear drive link rotatable, critical piece is closed in case vivo environment adaptability By force, the control unit split-phase of cutter head is integrated in the crossbeam of each phase, and self-sustaining work(is realized with power source is detached from place Can, there is not security risk by installation foundation deformation and the variation of operating mechanism and transmission parts in operation, reduces operation The design of mechanism case is wanted, and is solved except the risk of an electric part pair second part is superimposed, is really realized non-maintaining, this design compensates for The various disadvantages of existing disconnecting switch among the above, the closure designs of integrated modular, the reliability for pre-adjustment of dispatching from the factory, scene are blind The risk factor of dress removal human factor, promotes to realize the power grid regulation process of integration, and price is opened with existing high_voltage isolation It closes quite, there is instead revolutionary technological break-through completely.
