Description

Technical Field

[0001] The present invention relates to the technical field of power transmission equipment, and particularly relates to a plugging device for a distribution module. Background Art

[0002] The busbar trunking system is a highly efficient power distribution system widely used in the power distribution systems of high-rise buildings and large-scale factories. It has the advantages of large current-carrying capacity, high protection level, convenient power distribution, compact structure, and long service life. In the engineering projects of indoor low-voltage power transmission main lines, the way of the busbar trunking system to transmit electric energy gradually replaces the way of using wires and cables to transmit electric energy.

[0003] As a supporting unit of the busbar trunking system, the plugging device for the distribution module plays a role in distributing electric energy in the busbar trunking system.

[0004] For the plugging between the plugging device of the traditional busbar trunking system and the main trunk of the busbar trunking system, generally, it is the plugging between a copper bar and a rolled copper strip. Due to the influence of production processes and processing precision, etc., it is impossible to ensure the clamping contact gap between the copper strip and the copper bar. In the case of high load, the temperature of the contact area will rise. The copper strip is prone to generate internal stress when heated, resulting in an excessive contact gap and poor contact, which causes the equipment to be unable to take power and operate normally.
