Abstract
A kind of breaker bolts metallic laminas installs wavy metallic laminas on the cabinet including cabinet body and by bolt, is provided with locating rod in the upper through-hole of metallic laminas, is equipped with elastic mechanism and fixed plate in the locating rod 3 on the downside of metallic laminas.The invention has the following beneficial effects: by installing friction grounding elastic body on switchgear, make its no matter operating status or can be whole in the state of exiting guarantee reliable ground, to avoid electrical metal shell charges and causes personal safety accident.
Description
Technical field
The present invention relates to a kind of earthing or grounding means more particularly to a kind of breaker bolts metallic laminas.
Background technique
Its structure of traditional earthing or grounding means is contact type design, when technical staff operates electric device, only true
The operating position cut reliable ground and could play the protective effect of electrical metal shell, make it without dangerous to human body
Electric shock voltage.But when electric device is out of service, which is not connected to ground, cannot reliably guarantee operator
Personal safety, be easy to causeing leads to the casualty accident of operator because of metal shell electrification.In order to improve existing contact
The outer casing electrification of unreliable ground connection bring metal of the earthing mode of formula when electric device is out of service causes personnel hazard
The problem of, no matter switchgear friction earthing device of the present invention is in the guarantor for running or can be whole under the operating status exited
Reliable ground is demonstrate,proved, to reach life safety caused by electrical metal shell charges.
Summary of the invention
The object of the present invention is to provide one kind reach the electric device no matter run or exit state can be by close
It is reliable to rub to achieve the purpose that the breaker bolts metallic laminas of ground connection.
To achieve the above object, the invention is realized by the following technical scheme: being mounted on including cabinet body and by bolt
Wavy metallic laminas on cabinet body is provided with locating rod, the positioning on the downside of metallic laminas in the upper through-hole of metallic laminas
Elastic mechanism and fixed plate are installed on bar.
The present invention makes no matter it in operating status or is exiting by installing friction grounding elastic body on switchgear
State can be whole guarantee reliable ground, cause personal safety accident to avoid the electrification of electrical metal shell.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, the wavy metallic laminas that the present invention includes cabinet body 1 and is mounted on cabinet body 1 by bolt 7
2, it is provided with locating rod 3 in the upper through-hole of metallic laminas 2, elastic mechanism 4 is installed in the locating rod 3 of 2 downside of metallic laminas
And fixed plate 5, wiring 6 are connect with metallic laminas 2.
