Description

TECHNICAL FIELD

[0002] In modern power systems, the switching control of various electrical equipment (such as capacitors, reactors, etc.) is a very important link. When the traditional mechanical switch is switched, an arc is often generated, which not only causes wear and tear to the switch itself, affecting its service life, but also may cause a series of electrical problems, such as voltage sag, electromagnetic interference, etc., which adversely affect the stable operation of the power grid. In recent years, with the development of electronic technology, silicon controlled rectifier devices have been gradually applied to the switching switch field. Silicon controlled rectifiers have the advantages of fast response speed and no contact, and can overcome the defects of mechanical switches to some extent.

[0003] For the related technology in the above, the inventor believes that the existing silicon controlled rectifier zero-crossing switching switch is usually fixed on the bracket during installation, and daily maintenance requires disassembly and assembly. The traditional fixing method is not convenient for workers to disassemble and assemble, which reduces the daily maintenance efficiency. Therefore, the silicon controlled rectifier zero-crossing switching switch is proposed to solve the above problems.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it can include prior art known to those skilled in the art. CONTENT OF THE UTILITY MODEL

[0008] Preferably, the driving assembly comprises a plurality of brackets, the plurality of brackets are respectively fixed to the outer wall of the mounting frame, the outer wall of each of the plurality of brackets is rotatably connected with a driving frame, a connecting frame is arranged between the driving frame and the telescopic rod, and the connecting frame is hingedly connected with the driving frame and the telescopic rod.

[0009] Preferably, the two side outer walls of the fixed frame are provided with limiting grooves.

[0010] Preferably, the outer wall of the driving frame is fixedly connected with a handle.

[0011] To sum up, the present application has the following beneficial technical effects:

[0012] The bottom mounting block is connected with the fixed groove through the fixed frame, and the limiting groove positions the mounting block, and then the driving assembly drives the surrounding telescopic rods to expand and contract, so that the telescopic rods are connected with the two side fixed grooves, thereby fixing the mounting block and realizing the quick disassembly and assembly of the switch body. Compared with the prior art, the controllable silicon zero switching switch can be quickly disassembled and assembled, which is convenient for workers to operate, thereby facilitating the subsequent workers to maintain the controllable silicon zero switching switch and improving the maintenance efficiency.
