Abstract

The utility model reveals a terminal box anti-electric-shock separator plate. Bus supports fix busbars in the terminal box and a switch group support fixes an air switch in the terminal box. An insulating separator plate is arranged between the door of the terminal box and the busbars, and is fixed to the bus supports through supporting columns. The terminal box anti-electric-shock separator plate has advantages of simple structure, easy installation, and economical and attractive characteristics, satisfies an anti-electric-shock requirement in daily work while not influencing daily tour inspection and maintenance operation, and may effectively prevent a worker from contacting a live naked wire or connector by mistake while working in the terminal box and prevent low-voltage electric shock accidents.

Description

A terminal box anti-shock partition

technical field

The utility model relates to an insulation protection mechanism for electrical equipment.

Background technique

The outdoor terminal box of the substation is an important equipment of the substation, and it is a transfer station connecting the primary and secondary equipment. With the improvement of technology and the demand of on-site load, the 220kV substation and the outdoor terminal box of 110kV substation put into operation in recent years all adopt the structure of three-phase low-voltage busbar, which not only improves the low-voltage capacity, but also greatly facilitates installation and maintenance. Wiring specifications are neat and clear. However, the centralized power supply design makes the exposed part of the busbar very close to the low-voltage air switch in the terminal box; in addition, according to relevant regulations, devices with busbars in the electronic circuit need to use copper bars and add jacket. However, in the actual installation, wiring and daily maintenance process, the busbars are fixed by bolts, and the joints such as perforated wiring cannot be fully covered with sheaths and are exposed, which will pose a threat to the life safety of the daily work of the staff.

Utility model content

The technical problem to be solved by the utility model is to realize a safety protection device applied in a terminal box.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a terminal box anti-shock partition, the bus bar bracket and the switch group bracket respectively fix the bus bar and the air switch group in the terminal box, and the terminals An insulating partition is arranged between the box door of the box and the busbar, and the insulating partition is fixed on the busbar support through the support column.

The insulating partition is a transparent partition.

An insulating sheath is provided at the end of the supporting column near the box door.

There are two busbar brackets, and each busbar bracket is provided with two supporting columns for supporting the insulating partitions. The supporting columns are threaded columns, and the two ends are respectively fixed by nuts on the insulating partition and on the busbar. on the stand.

The utility model has the advantages that the device has a simple structure, is convenient to install, and is economical and beautiful. In addition to meeting the requirements for preventing electric shocks in daily work, it does not affect the daily inspection and maintenance work, and can effectively prevent staff from working in the outdoor terminal box. Accidentally touch live wires or connectors to avoid low-voltage electric shock accidents.

Description of drawings

The following is a brief description of the content expressed in each piece of drawings in the specification sheet of the utility model and the marks in the figure:

Figures 1 and 2 are schematic diagrams of the structure of the anti-shock partition installed in the terminal box;

The marks in the above figures are: 1. Busbar bracket; 2. Busbar; 3. Switch group bracket; 4. Air switch group; 5. Insulation partition; 6. Support column; 7. Box door.

Detailed ways

Referring to Figures 1 and 2, it can be seen that the busbar 2 and the air switch group 4 are arranged in the terminal box through the busbar bracket 1 and the switch group bracket 3, and the insulating partition 5 is arranged between the door 7 of the terminal box and the busbar 2, which passes through The support column 6 is fixed on the bus bar support 1 . There are two busbar brackets 1, and each busbar bracket 1 is provided with two supporting columns 6 for supporting the insulating partition 5, and the insulating partition 5 is fixed by four-point fixing. The supporting columns 6 are threaded columns, and the two ends The insulating partitions 5 and the busbar support 1 are respectively fixed by nuts. In addition, in order to further improve the safety performance, an insulating sheath is provided at the end of the support column 6 close to the box door 7 .

The insulating partition 5 is preferably an acrylic transparent plate, and the size is cut according to the installation form of the on-site busbar, so as to cover the busbar and ensure that personnel do not accidentally touch it. The transparent insulating partition 5 can not only ensure the safety of the staff, It can also clearly observe the operating conditions of the equipment.

The present invention has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-mentioned manner, as long as various insubstantial improvements are carried out by adopting the method concept and technical solutions of the present invention, or without Improvements that directly apply the concept and technical solutions of the present invention to other occasions are within the protection scope of the present utility model.
