Description

630A drawer switch assembly in 0.4kV-GCK cabinet with dual connectors

technical field

The utility model relates to a 630A drawer switch assembly in a 0.4kV-GCK cabinet with double connectors.

Background technique

The 0.4kV-GCK cabinet/630A drawer switch assembly is widely used in the power distribution cabinet of the distribution network. The functional unit of the cabinet body adopts a drawer structure and an insertion structure, which makes maintenance safe and convenient, can shorten the power failure time in an accident, and has the advantages of simple operation of the drawer, With strong interchangeability, the connection between the switch assembly and the power side and load side busbars adopts a single set of connectors.

The shortcomings of the existing technology: the 630A drawer switch assembly in the 0.4kV-GCK cabinet adopts a single set of connectors, and the contact area between the connectors and the busbar is small. When the current is large, the temperature of the connectors rises quickly, and the operation When the temperature rises to a certain level and runs for a certain period of time, the pressure of the clamping spring will attenuate, so that the contact efficiency of the connector will be lower, and the connector will burn out due to arcing and cause a short circuit until the equipment is damaged, which affects the reliability of power supply. This is a congenital defect in the design of the existing 630A drawer switch assembly.

Utility model content

The purpose of the utility model is to provide a 630A drawer switch assembly in a 0.4kV-GCK cabinet with double connectors.

The utility model is realized through the following technical solutions: a 630A drawer switch assembly in a 0.4kV-GCK cabinet with double connectors, including an assembly panel, an assembly back plate, an assembly side plate, an assembly frame, a load Side busbar connectors, power side busbar connectors, power side busbar protection frames, load side busbar protection frames, air switches and operating mechanisms arranged on the assembly panel, the assembly panel, the assembly back panel 1. The side plate of the assembly and the frame of the assembly constitute the drawer of the switch assembly. The busbar connectors on the load side and the busbar connectors on the power supply side are arranged in the through holes of the backplane of the assembly. The protective frame of the busbar on the power supply side and the load-side busbar protection frame are arranged on the outside of the assembly backplane and correspond to the positions of the power-side busbar connectors and the load-side busbar connectors respectively, and the load-side busbar connectors and the power-side busbar connectors are respectively Two groups, each group of load-side busbar connectors and power-side busbar connectors are connected to the air switch through copper busbars.

The two sets of power-side busbar inserts are arranged side by side from top to bottom, and the two sets of load-side busbar inserts are arranged side by side from top to bottom.

An ammeter and an observation window for an indicator light are arranged on the assembly panel.

The copper busbar is a prefabricated copper busbar.

Compared with the 630A drawer switch assembly in the existing 0.4kV-GCK cabinet, the utility model has the following advantages:

The utility model is provided with two sets of load-side busbar plug-ins and power-side busbar plug-ins, thereby increasing the contact area between the switch assembly and the incoming and outgoing line busbars, reducing the operating temperature, and maintaining the clamping spring pressure of the connectors, thereby increasing the contact area of the connectors. Contact efficiency, improve the reliability of power supply operation.
