Description

Anti-mis-opening device for the isolation baffle of the metal armored central removable switchgear

1. Technical field: The utility model relates to a switchgear in an electric power system, in particular to a device for preventing accidental opening of an isolation baffle of a removable switchgear in the middle of the metal armor.

2. Background technology: With the rapid development of the electric power industry, the application of metal armored central removable switchgear in the electric power system is more and more extensive. The switch cabinet is composed of two parts: a fixed cabinet and a drawable part (referred to as a handcart). The trolley can move between working position and test/isolation position. The isolation baffle is made of metal plate and installed on the rear wall of the handcart room. When the handcart moves from the isolation/test position to the working position, through the transmission mechanism, the isolation baffle in front of the static contact box installed in the busbar chamber and the cable room is automatically opened, and the handcart is moved in the opposite direction. The isolation baffle is automatically closed to seal the static contact box, so as to ensure that the operator does not touch the charged body. But when the staff enters the switch cabinet to deal with defects and touch the isolation baffle by mistake, the isolation baffle is opened, causing the human body to have insufficient safety distance from the charged body and electric shock accidents.

3. Contents of the utility model:

The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art, to provide a simple structure, easy to operate, firmly clamped and safe to use, and to prevent misopening of the isolation baffle of the removable switch cabinet in the middle of the metal armor device.

The technical scheme of the utility model is: an anti-mis-opening device for the isolation baffle of the removable switch cabinet in the middle of the metal armor, which includes a clamping plate, an L-shaped clamping arm and a connecting plate, and the two ends of the connecting plate are respectively connected to a One end arm of the L-shaped clamping arm is connected, and the other end arm of the L-shaped clamping arm is connected with the middle part of one of the clamping plates, and a clamping bolt is respectively provided at both ends of the clamping plate.

The other end arm of the L-shaped clamping arm is connected with the middle part of the clamping plate through a rivet. There are at least two rivets.

The connecting plate and the L-shaped clamping arm are respectively provided with bolt holes, and the two are fixed together by connecting bolts. The bolt holes on the L-shaped clamping arm are bar-shaped holes.

The beneficial effects of the utility model are:

1. The utility model starts from the transmission mechanism of the locking isolation baffle, matches the original transmission mechanism, and is firmly clamped. After the transmission mechanism of the isolation baffle is locked, the isolation baffle cannot be opened from all aspects, so that The occurrence of electric shock accidents caused by people touching the isolation baffle is avoided, and the personal safety of electric workers is guaranteed.

2. The installation time of the utility model is less than 60 seconds, the efficiency is high, and the distance between the staff and the charged static contact is greater than 0.35m during installation, which meets the requirements of the "Regulations on Safe Production Work in the Electric Industry".

3. The L-shaped clamp arm of the utility model is provided with a strip hole, which is convenient for adjusting the distance between the clamps at both ends, so as to meet the requirements of different distances. In addition, the L-shaped clamping arm and the connecting plate are fixed by connecting bolts, which can be disassembled and assembled, and are convenient for manufacture, storage and transportation.

4. The utility model has the advantages of simple structure, easy operation, firm clamping and safe use, wide application range, and good economic benefits after popularization.

Fig. 2 is a top view of the utility model.

5. Specific implementation methods:

Embodiment: See Figure 1 and Figure 2, in the figure, 1-clamping bolt, 2-clamping plate, 3-L-shaped clamping arm, 4-connecting bolt, 5-connecting plate, 6-rivet, 7-bar-shaped hole .

The anti-mis-opening device of the isolation baffle of the metal armored central removable switchgear includes a clamping plate 2, an L-shaped clamping arm 3 and a connecting plate 5, and the two ends of the connecting plate 5 are respectively connected with one end arm of an L-shaped clamping arm 3 , the other end arm of the L-shaped clamping arm 3 is connected with the middle part of a clamping plate 2, and a clamping bolt 1 is arranged at both ends of the clamping plate 2 respectively.

According to requirements, the other end arm of the L-shaped clamping arm 3 is connected to the middle part of the clamping plate 2 with a rivet 6, and there are at least two rivets 6; of course, welding or bolting can also be used.

The connecting plate 5 and the L-shaped clamping arm 3 are respectively provided with bolt holes, and the two are fixed together by connecting bolts 4 . According to needs, the bolt holes on the L-shaped card arm 3 are strip holes 7, which is convenient for adjusting the length of the whole device.

When in use, according to the distance between the left and right horizontal crank arms of different switch cabinets, adjust the fixed position between the L-shaped clamp arm 3 and the connecting plate 5, so that the fastening bolts 1 on the two clamp plates 2 are respectively inserted into the left and right horizontal crank arms In the locking hole of the drive mechanism, the up and down movement of the horizontal crank arm of the transmission mechanism is restricted, so that the isolation baffle cannot be opened, and then the connecting bolt 4 is tightened to complete the installation.

According to needs, a strip-shaped hole can also be provided on the clamping plate 2, and the fastening bolt 1 is located in the strip-shaped hole, and the up and down installation position can be adjusted, and the application range is wider.
