Special tools for handcart switch and grounding knife switch operation

Abstract

The invention discloses a handcart switch and grounding switch operation special tool, which comprises a handcart switch operation mechanism, a grounding switch operation mechanism and a handle, wherein the handcart switch operation mechanism comprises a handcart switch sleeve; a handcart switch operation head is arranged at the outer end of the handcart switch sleeve in a rotating mode; a tension overload automatic release is arranged between the handcart switch operation head and the handcart switch sleeve; the handcart switch sleeve is internally provided with a driving motor; the grounding switch operation mechanism comprises a grounding switch sleeve; a grounding switch operation head is arranged at the outer end of the grounding switch sleeve in a rotating mode; a spring energy storage mechanism is arranged inside the grounding switch sleeve; and a rotating lock switch and an operation head switch are arranged between the grounding switch operation mechanism and the handcart switch operation mechanism. Corresponding operation of the handcart switch or the grounding switch is realized in an electric or manual control mode, the operation and the use are convenient, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of power transmission and distribution tools, in particular to a special tool for operating a handcart switch and a grounding knife switch. Background technique [0002] With the transformation of intelligent substations, handcart switches are widely used in substations. Pushing in and pulling out switches requires manual rotation of the handle to change the handcart from one equipment state to another. According to estimates, the 35kV handcart equipment needs to shake the handcart handle for about 30 turns on average in the operation of the substation, and the 10kV handcart switch needs about 15-20 turns. An ordinary 35kV substation generally has 35kV, 10kV switches, lightning arresters, TVs, etc. There are about 30 sets of handcart equipment, and all power-off operations require shaking the handle 500-600 times, which requires one person to complete the operation within 1 hour. The same is true for the op...

Problems solved by technology

[0003] When performing the above operations, the staff must bring a lot of equipment and appliances to the operation site, such as handcart handles, special grounding knife switch operating tools, insulating operating gloves, operating tickets, various unlocking keys, recording equipment, lighting equipment, etc. , the handcart handle and the special grounding knife switch operation sleeve are iron tools, heavy, and not insulated. Pull out or push in the handcart according to the operation instructions, and the grounding knife switch needs a handcart crank to close or pull it out. And special grounding knife switch operation sleeve, exchange operation, the workload is huge, the tool is not insulated and it is not safe, the whole process of operation needs to be recorded, check whether the operating equipment is in place, because the switch cabinet is completely closed, the inside of the switch cabinet is dark, so lighting equipment is required And recording equipment, there is no comprehensive functional handcart handle and special tool for grounding knife switch operation in the market
