Abstract
The utility model relates to a circuit breaker friction grounding device, comprising a metal guide plate, an elastic mechanism and a fixing plate, the metal guide plate is a waveform structure and is arranged on a cabinet body by a bolt, a locating rod is arranged in a through hole at the upper part of the metal guide plate, and the lower side of the metal guide plate is connected with the elastic mechanism. The circuit breaker friction grounding device has the beneficial effects that: the friction grounding elastic mechanism is arranged on a switch cabinet, so as to ensure reliable grounding in the whole course no matter in a running state and an exit state, so as to avoid electrification of an electrical metal shell and cause personal safety accidents.
Description
Technical field
The utility model relates to a kind of earthing device, relates in particular to a kind of friction earthing device for disconnector.
Background technology
Its structure of traditional earthing device is contact type design, when technical staff's operate electrical devices, only could reliable ground and play the protective effect of electric metal shell in definite service position, and it is not had the adventurous electric shock voltage of human body.But when electric device was out of service, this contact type earthing device did not connect ground, can not reliably guarantee operating personnel's personal safety, caused the casualty accident because of the charged operating personnel of causing of metal shell easily.The outer casing electrification of the metal that brings for the unreliable ground connection of earthing mode when electric device is out of service of improving existing contact type causes the problem of personnel's danger, the utility model switch cubicle friction earthing device no matter can omnidistance assurance reliable ground under the running status that operation is still being withdrawed from, to reach the electric charged life safety that causes of metal shell.
The utility model content
At above defective, the purpose of this utility model provides a kind of friction earthing device for disconnector that the friction grounding elastic body is installed on switch cubicle, to reach this electric device no matter all can be by closely rubbing to reach the purpose of ground connection reliably in operation or exit status.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of friction earthing device for disconnector comprises metallic laminas, elastic mechanism and fixed head, and described metallic laminas is wavy shaped configuration and is installed on the cabinet by bolt; Establish backstay in the top through hole of described metallic laminas, the downside of metallic laminas connects the elastic mechanism of being made up of spring, and the bottom of described elastic mechanism is connected and fixed plate.
The beneficial effect of friction earthing device for disconnector described in the utility model is: by the friction grounding elastic body is installed on switch cubicle, make it no matter still can omnidistance assurance reliable ground in exit status in running status, charged and cause the personal safety accident to avoid electric metal shell.
Description of drawings
According to embodiment and accompanying drawing the utility model is described in further detail below.
Fig. 1 is the structural representation of the described friction earthing device for disconnector of the utility model embodiment.
Among the figure:
1, cabinet; 2, metallic laminas; 3, backstay; 4, elastic mechanism; 5, fixed head; 6, wiring; 7, bolt.
Embodiment
As shown in Figure 1, friction earthing device for disconnector described in the utility model comprises metallic laminas 2, elastic mechanism 4 and fixed head 5, and described metallic laminas 2 is installed on the cabinet 1 for wavy shaped configuration and by bolt 7; Establish backstay 3 in the top through hole of described metallic laminas 2, the downside of metallic laminas 2 connects the elastic mechanism of being made up of spring 4, and the bottom of described elastic mechanism 4 is connected and fixed plate 5; Described wiring 6 is connected with metallic laminas 2.
The advantage that more than shows and described principal character of the present utility model and had.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; the utility model also has some variations and improves under the prerequisite that does not break away from the utility model purport and scope, and these changes and improvements all fall in claimed the utility model scope.
