The system of 12kV and 7.2kV three-phase alternating current 50Hz is widely used especially；The ground connection of Medium Voltage Switchgear at present
Switch with front Xiamen be typically not provided with interlocking mechanism, when switch cubicle is designed to mounted against a wall, front lower room with
Cable vault communicates, and therefore when earthed switch is in gate-dividing state, the front Xiamen of switch cubicle can arbitrarily be beaten
Opening, this brings great hidden danger to the safe operation of switch cubicle；If operation and maintainer are at charged shape
Open front Xiamen under state by mistake, the situation of injury to personnel and device damage will be easily caused.
Switch cubicle also has employing mechanical interlock mechanism to prevent front lower room door from being opened by mistake at present；But chain not
Reliably, install and need to adjust, and also to prepare special emergency release handle, when needing emergency release, as
Without dedicated handle, front Xiamen is difficult to unblock and opens；This type of interlocking mechanism's linkage is not strong, and security performance is not good enough.
Utility model content
It is strong that the purpose of this utility model is to provide linkage, the one front lower room door earthed switch that security performance is high
Interlocking mechanism.
The technical solution of the utility model is as follows:
A kind of front lower Shi Men earthed switch interlocking mechanism, including ground connection main shaft, interlock plate, lock shaft, first
Frame；It is provided with the first support and lock shaft below the door ground connection main shaft end of described front lower room；Described interlock plate passes through
Guider is movably disposed on the first support, this interlock plate end offer with lock shaft with the use of U
Shape groove；The driving means driving interlock plate to move it is provided with between described first support and ground connection main shaft.
Described driving means includes the ground strip being located on ground connection main shaft end, is arranged on answering on the first support
Position spring and the second support being arranged on the first support through back-moving spring；Described ground strip and ground connection master
Eccentric shaft is arranged.Owing to ground strip and ground connection main shaft use eccentric setting, therefore drive ground connection when ground connection main shaft
When sheet rotates, the long end of ground strip will press interlock plate down, to be unlocked by lock shaft；And by arranging reset
Spring, in order to when pressing interlock plate under the short end of ground strip, lock shaft is locked by Rapid reset.
Described guider includes upper fluting that interlock plate top arranges and lower fluting, and this upper and lower fluting is the most logical
Cross gag lever post to be arranged on the first support.Owing to upper and lower fluting is all arranged on the first support by gag lever post,
Therefore when interlock plate moves up and down, upper and lower fluting also will move along gag lever post, and this gag lever post is on the one hand
Play the guide effect to interlock plate, on the one hand play spacing effect.
Described lock shaft is cylindrical, and this lock shaft one end offers screwed hole.Owing to being threaded in lock shaft one end
Hole, when the needs that are in an emergency carry out emergency release to front Xiamen, is being not required to be equipped with the feelings of specific purpose tool
Under condition, only the bolt outside lock shaft need to be unloaded and front lower room door can be carried out emergency release.
The beneficial effects of the utility model are: interlock plate front end is flanging form, are positioned under ground connection locking plate
Side, when earthed switch turns to closing position from sub-gate position or turns to sub-gate position from closing position, ground connection main shaft
Drive ground strip rotates, and ground strip is pushed down interlock plate and moved downward or upward, and the U-type groove of interlock plate end is i.e.
Lock shaft can be realized locking or unlock, thus realize front lower room door and earthed switch interlocking machine so that this practicality
New structure is simple, easy for installation, safe and reliable, and linkage performance is good, perfect in shape and function, and the later stage overhauls
Easy to maintenance.
Accompanying drawing explanation
By detailed description below in conjunction with the accompanying drawings, this utility model is aforesaid and other purpose, feature and
Advantage n will become clear from.
Wherein: Fig. 1 is this utility model embodiment 1 structural representation；
