Abstract
The utility model discloses a kind of high-voltage board ground switch interlocking device, including be installed on the indoor electromagnetic lock of the cabinet lateral wall of high-voltage board, and it is arranged on the earthed switch of the locking bar side of described indoor electromagnetic lock, expose the useful shell fragment opening or closing in earthed switch in the handle hole of described earthed switch；When described high-voltage board is charged, the locking bar of described indoor electromagnetic lock ejects, and then stops that described shell fragment moves downward, and now earthed switch is closed；When described high-voltage board is not charged, the locking bar of described indoor electromagnetic lock is retracted, and then described shell fragment is moved downward, and now earthed switch is in open mode.Indoor electromagnetic lock and the setting of shell fragment, when can be prevented effectively from electric interlock inefficacy, grounding misoperation switchs.
Description
Technical field
The utility model relates to high-voltage board technical field, particularly relates to a kind of high-voltage board ground switch interlocking device.
Background technology
Under prior art, the earthed switch that some high-voltage board incoming line cabinets are installed is not owing to having mechanical interlocking, at electric interlock
It during inefficacy, is easily caused maloperation, in turn result in bigger potential safety hazard.
Utility model content
The purpose of this utility model is to provide one to be prevented from maloperation, safe and reliable high-voltage board earthed switch connection
Locking device.
For reaching this purpose, the utility model by the following technical solutions:
A kind of high-voltage board ground switch interlocking device, including be installed on the indoor electromagnetic lock of the cabinet lateral wall of high-voltage board,
And be arranged on the earthed switch of the locking bar side of described indoor electromagnetic lock, expose in the handle hole of described earthed switch useful in
The shell fragment that earthed switch opens or closes；
When described high-voltage board is charged, the locking bar of described indoor electromagnetic lock ejects, and then stops that described shell fragment moves downward,
Now earthed switch is closed；
When described high-voltage board is not charged, the locking bar of described indoor electromagnetic lock is retracted, and then described shell fragment is transported downwards
Dynamic, now earthed switch is in open mode.
Wherein, the downside of described handle hole offers the fluting for matching with described shell fragment.
Wherein, be provided with high pressure sensor in described high-voltage board, described high pressure sensor with for and described indoor electromagnetism
The electric control gear of phase-locked connection is connected.
Wherein, described indoor electromagnetic lock is provided with unlocking indicator lamp.
Wherein, the L-shaped setting of described shell fragment, and described shell fragment is connected with the ground connection device being arranged on earthed switch rear
Connect.
The beneficial effects of the utility model: the utility model includes the indoor electromagnetism being installed on the cabinet lateral wall of high-voltage board
Lock, and it is arranged on the earthed switch of the locking bar side of described indoor electromagnetic lock, exposing in the handle hole of described earthed switch has
The shell fragment opening or closing for earthed switch；When described high-voltage board is charged, the locking bar of described indoor electromagnetic lock ejects, and then
Stopping that described shell fragment moves downward, now earthed switch is closed；When described high-voltage board is not charged, described indoor electricity
The locking bar of magnetic padlock is retracted, and then described shell fragment is moved downward, and now earthed switch is in open mode.Indoor electromagnetic lock and
The setting of shell fragment, when can be prevented effectively from electric interlock inefficacy, grounding misoperation switchs.
Brief description
Fig. 1 be the utility model a kind of high-voltage board ground switch interlocking device mesohigh cabinet charged when axonometric drawing.
Fig. 2 be the utility model a kind of high-voltage board ground switch interlocking device mesohigh cabinet not charged when axonometric drawing.
Detailed description of the invention
Below in conjunction with the accompanying drawings and further illustrate the technical solution of the utility model by detailed description of the invention.
In conjunction with shown in Fig. 1 and Fig. 2, a kind of high-voltage board ground switch interlocking device in the present embodiment, including be installed on high pressure
The indoor electromagnetic lock 1 of the cabinet lateral wall of cabinet, and it is arranged on the earthed switch 2 of the locking bar side of described indoor electromagnetic lock 1, institute
The useful shell fragment 3 opening or closing in earthed switch 2 is exposed in the handle hole stating earthed switch 2；When described high-voltage board is charged,
The locking bar of described indoor electromagnetic lock 1 ejects, and then stops that described shell fragment 3 moves downward, and now earthed switch 2 is in cut out shape
State；When described high-voltage board is not charged, the locking bar of described indoor electromagnetic lock 1 is retracted, and then described shell fragment 3 is moved downward,
Now earthed switch 2 is in open mode.Design in this way, maloperation can be prevented effectively from, and then play effective safety
Protective action.
In the present embodiment, the downside of described handle hole offers the fluting 4 for matching with described shell fragment 3.Described height
It is provided with high pressure sensor, described high pressure sensor and the electric control gear being used for and described indoor electromagnetic lock 1 is connected in pressure cabinet
It is connected.It is provided with unlocking indicator lamp 11 on described indoor electromagnetic lock 1.The L-shaped setting of described shell fragment 3, and described shell fragment 3 with set
Put the ground connection device at earthed switch 2 rear to be connected.
Said structure designs, and effectively can be prevented to shell fragment maloperation by the setting of indoor electromagnetic lock, and then forms peace
Full hidden danger.
Describe know-why of the present utility model above in association with specific embodiment.These descriptions are intended merely to explain this reality
By novel principle, and the restriction to the utility model protection domain can not be construed to by any way.Based on explanation herein,
Those skilled in the art does not needs to pay performing creative labour can associate other detailed description of the invention of the present utility model,
These modes fall within protection domain of the present utility model.
