The tradition by-pass method is a lot, and relatively more commonly used is that two cover isolation switchs are set, the closed by-pass knife switch of elder generation when the needs repair apparatus, and then the disconnecting link of disconnection and devices in series.The shortcoming of doing like this is that two cover isolation switchs are separation equipments, and operation is independent, and order must be operated in accordance with regulations.If operating sequence is opposite, then whole electric power system produces very serious consequence with power down.In order to stop the generation of this situation, just need two cover disconnecting link combined operations, have only when a disconnecting link is in closure state, just another disconnecting link can carry out opening operation.
The utility model content
The purpose of this utility model is; above-mentioned defective at the prior art existence; a kind of double-pole interlocking-type power switch is provided; this power switch utilizes two disks that have circular arc cutaway with two isolation switch operating process interlockings; when having only one of them isolation switch to be in closure state; another isolation switch just can carry out opening operation; also promptly two isolation switchs can be in closure state simultaneously; but can not be in off-state simultaneously; therefore can effectively stop the situation that whole power circuit power down is withdrawed from; protect whole electric power system, highly improved the reliability of electric power system.
A kind of double-pole interlocking-type power switch that the utility model provides, its improvements are that described power switch comprises disconnecting link, operating handle, related dish, connecting rod and support; One end of described support connects with connecting rod and can rotate with connecting rod, and the other end of support is connected with disconnecting link; One end of described connecting rod is provided with operating handle, and the other end is provided with related dish; Described related dribbling has arc gap, by the turned position of operating handle control arc gap, thereby makes disconnecting link be in closure state simultaneously.
The first preferred double-pole interlocking-type power switch that the utility model provides, the number of described disconnecting link is 2, all corresponding 2 support bars of each disconnecting link and 1 support.
The second preferred double-pole interlocking-type power switch that the utility model provides, the arc gap number of described related dish is 4.
The 3rd preferred double-pole interlocking-type power switch that the utility model provides, the number of described operating handle is 2.
The 4th preferred double-pole interlocking-type power switch that the utility model provides, the corresponding disk independently of per 2 arc gaps of described related dish.
The 5th preferred double-pole interlocking-type power switch that the utility model provides, described support is connected by welding manner with connecting rod.
The 6th preferred double-pole interlocking-type power switch that the utility model provides, described support is made of the bar of two kinds of different materials, and the bar that is connected with connecting rod adopts ferrous materials, and the bar that is connected with disconnecting link adopts bakelite as material.
2 disconnecting links of the present utility model are in isolation, adopt two cover isolation switch combined operations, when a disconnecting link was in closure state, another disconnecting link can carry out opening operation, two isolation switchs can be in closure state simultaneously, but can not be in off-state simultaneously; The situation of so just having stopped whole power circuit power down takes place, and has improved the reliability of electric power system.
The chemical name of bakelite is in phenolic plastics, be that first drops into industrial kind in the plastics, it has higher mechanical strength, good insulation performance, heat-resisting, corrosion-resistant, therefore be usually used in making appliance material, as switch, lamp holder, earphone, telephone casing, meter housing etc., " bakelite " gains the name therefrom.
Compared with prior art, a kind of double-pole interlocking-type power switch of providing of the utility model has the following advantages:
1, adopt double-pole interlocking disconnecting link, simple to operate;
2, stop the situation that electric power system disconnects power down, the protection power equipment;
3, improve the stability of electric power system.
4, effectively stop the situation that whole power circuit power down is withdrawed from, protect whole electric power system, highly improved the reliability of electric power system;
5, manufacturing process is simple, practicality.
