Embodiment Construction

[0013] The operating tool for the circuit breaker in the switch cabinet of the present invention will be further described below in conjunction with the accompanying drawings. Such as figure 1 As shown, the operating tool used for the circuit breaker in the switch cabinet includes a handle 1 and a rotating shaft 2 parallel to the handle 1. A connecting rod 3 is arranged between the handle 1 and the rotating shaft 2, and the connecting rod 3 They can be connected by rotating connection to make the operation tools more convenient to use. One end of the rotating shaft 2 is connected to the connecting rod 3, and the other end of the rotating shaft 2 is provided with an operation part 4 that cooperates with the circuit breaker. The rotating shaft 2 The upper sleeve is provided with a bracket 5, which is rotatably connected with the rotating shaft 2, and the bracket 5 includes a sleeve 6 sleeved on the rotating shaft 2 and legs 7 evenly distributed on the circumference of the cross ...

Abstract

The invention provides an operating tool used for a breaker in a switch cabinet, a support sleeves a rotating shaft, and includes a sleeve that sleeves the rotating shaft and support legs uniformly distributed on the circumference of a cross section of the sleeve, an included angle between the support legs and the axis of the sleeve is 30 to 60 degrees, when the operating tool is utilized to operate the breaker, the operating tool can be conveniently positioned on the switch cabinet through the support, and operating structures of the rotating shaft and the breaker are guaranteed to be coaxial in a rotation process of the operating tool, so that the condition is avoided that when the operating tool is rotated, stress of the operating tool is nonuniform, causing the operating tool to be disengaged from the breaker, the operating tool is convenient to use and operation efficiency of the breaker is improved.

Description

technical field [0001] The invention relates to an operating tool for a circuit breaker in a switchgear. Background technique [0002] The trolley circuit breaker is a kind of power distribution component, which is widely used in the field of power grid. [0003] When operating a circuit breaker in the prior art, there are two methods for technicians to operate the circuit breaker, one is to operate directly; the other is to operate with the help of corresponding tools, because the circuit breaker needs to go through the energy storage stage during the operation process, therefore, the technician When operating the circuit breaker directly, it is difficult to operate the circuit breaker in place at one time. Generally, multiple operations are required to operate the circuit breaker in place. During this process, the contacts of the circuit breaker are in frequent contact, which can easily cause damage to the contacts of the circuit breaker. It may even damage the circuit br...
