Description
Technical field
The present invention relates to grounding switch ground detection device in transformer station, specifically a kind of novel grounded detection means.
Background technology
At present, a certain circuit of transformer station is changed to inspecting state or safety measure with carrying out splice grafting disconnecting link device is done in equipment power failure
When, it can only carry out whether subjective judgement grounding switch three-phase indeed closes by observing, if grounding switch phase sluice gate has rust
During the defects of erosion, gap, crackle, virtual ground phenomenon is often resulted in, great potential safety hazard, serious threat maintainer be present
Personal safety, there is not preferable solution so far.
The content of the invention
Present invention seek to address that it objective can not judge the whether just true ground connection of grounding switch, there is provided a kind of simple in construction, effect
Good grounding switch ground detection device.
The present invention is realized with following technical scheme：A kind of grounding switch ground detection device, including insulating bar, it is described
The lower end of insulating bar is provided with end cap, and the interior of the insulating bar is provided with ground wire, and the lower end of the ground wire is connected with earth clip, described
The upper end of ground wire is connected with the ground detection device for being arranged on insulating bar upper end, and the upper end of the ground detection device is provided with gold
Belong to contact flat spring, grounded inspection circuit is provided with the ground detection device.
It is further：The both ends of the grounded inspection circuit of the ground detection device are connected on ground wire respectively and metal connects
Touch shell fragment on, the grounded inspection circuit by ground wire to metal contact flat spring be sequentially connected in series power supply, triode, buzzer and
Light emitting diode, resistance is equipped between power supply and triode and between light emitting diode and metal contact flat spring.
The metal contact flat spring is the sheet metal of installation camber.
The present invention has advantages below：The novel grounded disconnecting link ground detection device of the present invention can be conveniently real by ground wire
The now connection of the device and grounded screen, earth point is provided for detection means, while ground detection device can be good in ground connection
In the case of acoustical signal and optical signal are provided, easy to operate, to grounding switch, whether good earth detects, and then ensures maintenance
Personnel's personal safety.

Resistance is equipped between metal contact flat spring 1.The grounded inspection circuit of the present invention is mainly by power supply, triode, buzzer and hair
Optical diode is formed, and resistance is provided with relevant position, A the and B ends that circuit is detected in figure contact with ground wire and metal respectively
Shell fragment links together, when ground wire and metal contact flat spring are respectively connected to the grounding switch of grounded screen and closure, Bian Ketong
Whether the break-make detection grounding switch for crossing whole circuit is really grounded, and sends signal by light emitting diode and buzzer, uses
It is whether effective with prompting ground connection.
Grounding switch ground detection device as shown in Figure 1 to Figure 2, the metal contact flat spring 1 are installation camber
Sheet metal.The lower end of the metal contact flat spring of the present invention is fixed on the top of ground detection device, and metal contact flat spring is solid
Fixed place's bending camber, when contact surface is arc, can preferably be contacted, when metal contact flat spring touches plane, by
Be sheet metal in metal contact flat spring, somewhat can be firmly in close contact with plane, thus metal contact flat spring and cambered surface and
Plane can be preferably bonded.
