Description

Main console terminal box in substation

technical field

The utility model relates to the field of electric equipment, in particular to a terminal box for a main console in a substation.

Background technique

The substation main console is the core workplace for centralized monitoring, maintenance and operation of substation equipment. In order to ensure the reliable operation of the main console host, it is powered by the UPS in the substation. UPS is an uninterruptible power supply device. When the power failure in the substation, it can start the battery to supply power to the important equipment in the substation. However, the outgoing line of UPS equipment is hard-wired, while the power supply connection line of the main console is soft-wired, and there is no special clamp or other device to connect the two cables, resulting in mixed connection of soft and hard lines. The outgoing cable of the UPS power supply is a BV line, that is, a plastic copper line, which is a single-core hard conductor power cable. The main console equipment power cord is BVR wire, that is, soft plastic copper wire, which is a copper core PVC insulated flexible wire. The R in the abbreviation BVR stands for soft wire, so in order to distinguish the two types of wires, they are called hard wire and soft wire respectively. The connection method of the soft and hard wiring of the main console is often simply wrapped with insulating tape. This simple way of dealing with wiring often leads to poor contact of wires and overheating of joints. Since the main console equipment needs to run for a long time, the existence of these hidden problems may cause power failure, and even cause a fire in severe cases.

Utility model content

The technical problem to be solved by the utility model is to provide a terminal box for the main console in the substation which can reasonably arrange various cables and improve the safety performance.

Therefore, the technical scheme of the utility model is as follows:

A main console terminal box in a substation, a box body, a box door and at least one terminal row, the box door is installed on the box body for opening or closing the box body, the box door is A handle with a lock is also installed, and the terminal block is installed horizontally on the inner wall of the box body opposite to the box door for the transfer between the hard cable and the soft cable. The inner wall facing the box door is provided with a ring-shaped wire slot around the terminal row, the bottom of the box body is provided with a wire inlet hole, and the side wall is provided with a wire outlet hole.

Wherein, the number of the terminal blocks may be two, and they are arranged in parallel with a preset distance up and down on the inner wall of the box body facing the box door.

The wiring terminal box of the main console in the substation in the utility model:

1) The box body, box door, terminal block, wire slot, wire inlet hole, and wire outlet hole are all professionally designed. The material of the box body is made of stainless steel, which makes it not only flexible, but also has high strength and rigidity. And has good anti-corrosion ability;

2) The box door is designed at the front end of the box body, and each lead-out line label corresponding to the terminal block is pasted on the inside of the box door, which can not only facilitate the inspection and elimination of fault points, but also facilitate daily inspection and maintenance;

2) The terminal block is divided into upper and lower layers. Two different types of terminal blocks, UTD- and UTD-, can be used, which are respectively suitable for wires with different rated currents. These two types of terminal blocks can well realize soft and hard wiring. The transfer increases the contact area between the two, reduces the contact resistance, and greatly alleviates the problem of overheating of the wire contacts.

3) The wire slots are arranged around the terminal block, which can fix the wires and cables, buffer the wires pulled by external force, and protect the wires well.

4) The wire inlet hole is at the bottom of the box, which is convenient for the UPS cable to lead directly from the floor to the terminal block, making the layout of the main console more reasonable and beautiful. isolation, and facilitate the connection of equipment.

In the utility model, all kinds of cables and wires are placed in the box, and the wiring of the main console can be reasonably arranged to reduce the wear of the wires in the arrangement, stepping on them in daily work, abnormal bending, etc., so that the main console The soft and hard wires between UPS and UPS can realize good connection, avoid problems such as poor contact and overheating of wire joints, so as to ensure the reliability and safety of various cable wires.

Through the utility model:

1) Realize the good transfer of the soft and hard wiring of the main console, avoiding the problems of poor contact and heating of the connector;

2) Reduce the wear and tear and bending of the wire, and improve the service life of the power supply;

3) Improve the aesthetics and practicability of the main console wiring;

4) Organized the wiring pattern and improved the efficiency of fault finding and troubleshooting;

5) Lock the door of the terminal box, establish a strict management mechanism, and increase the safety of work.
