Description

Complete set of switchgear assembled busbar bridge

Technical field:

The utility model relates to electric power transmission equipment, in particular to a novel complete switch cabinet assembly type busbar bridge.

Background technique:

The bus bridge, also known as the bridge connection, is used for the main wiring between the transformer and the switch cabinet, between the two sections of the bus, and between the overhead outlet cabinet and the line in the 35kV ~ 500kV substation. With the emergence of modern engineering facilities and equipment, the electricity consumption of all walks of life has increased rapidly, and many high-rise buildings and large-scale workshops have appeared. It cannot meet the requirements, and the parallel use of multiple cables brings a lot of inconvenience to the on-site installation and construction connection. As a new type of distribution wire, the busbar bridge has emerged at the historic moment. Compared with the traditional cable, it fully demonstrates its superiority in the transmission of large currents. The contact resistance and temperature rise of the internal connection and the branch outlet socket, and high-quality insulating materials are used in the bus bridge, thereby improving the safety and reliability of the bus bridge and making the whole system more perfect.

The busbar bridge currently in use in most areas is a welded busbar bridge, which is made of No. 5 angle steel welded frame and sealed with a cold plate with a thickness of 2mm to make a rectangular parallelepiped. The inner bracket supports the busbar. This type of busbar bridge is not only large in size and bulky in appearance, but also can only be welded on site, making installation extremely difficult. Its rigidity is poor, and the steel plate in the middle section is easy to fall. After the on-site installation, it must be fixed by drawing steel wires from the ceiling. In addition, it must be constructed on site. Due to the difficulty of installation, the required power outage period is long, which affects the electricity consumption of residents; auxiliary equipment cannot be used on site, and all construction is done manually, which causes a great waste of human resources; the materials of the welded bus bridge are heavy and heavy. High cost; heat dissipation holes cannot be processed after the busbar bridge is welded, so the heat dissipation effect is extremely poor.

The utility model fundamentally solves all the defects of the above welded bus bridge. The bridge shell is fully sealed, omitting the bulky angle steel, all made of cold-rolled steel plates, with smooth and beautiful appearance, novel structure and reasonable layout, compact structure and good sealing performance. The bridge shell has high and low temperature resistance, aging resistance, impact resistance, acid rain resistance, moisture resistance, corrosion resistance, heat dissipation and ventilation and resistance to external damage; it also has good ventilation, rain resistance, heat dissipation, and external damage resistance. The hanging ground wire device for maintenance is provided. It is suitable for the laying of various busbars in various projects, and has the advantages of simple structure, flexible configuration, convenient installation and novel form. It can design and manufacture each section of bridge frame according to the on-site design. It can be assembled and adjusted on-site without welding, and the construction and installation are very convenient.

Invention content:

In order to solve the defects of welded busbar bridge, this utility model provides an assembled busbar bridge, which solves the shortcomings of the existing welded busbar bridge, such as bulkiness, difficulty in installation, on-site construction, and long power outage.

A complete set of switchgear assembled busbar bridge is composed of incoming line cabinets, bridge piers, post insulators and plate bodies. The post insulator has multiple ventilation holes on the board body, and stainless steel wire mesh is welded in the ventilation holes.

The progress of the utility model lies in: adopting the assembled structure, the finished product can be processed and produced in the factory, and the on-site installation is enough, which greatly reduces the power outage time caused by the on-site construction compared with the past, and improves the power supply efficiency and reliability.
