Description

A new efficient heat dissipation busway joint device

technical field

The utility model mainly relates to the field of power distribution, in particular to a novel high-efficiency heat dissipation bus duct joint device.

Background technique

In the field of power distribution, as a device responsible for the transmission and distribution of electrical energy, the busbar has many advantages, such as large current carrying capacity, convenient installation, safety and reliability, and convenient distribution of electrical energy. In recent years, with the increasing demand for electricity, bus ducts are gradually used in large power supply equipment.

However, as a dense bus duct, there are some shortcomings in the transmission of current. For example, due to the large transmission current, the connector parts at the joints of each section of the dense bus duct are due to the conductive busbar and the conductive connection between the connector. The gap is unavoidable, and the heat level inside the connector is generally higher than that of the main part of the dense busway, while the insulating plate at the joint of the traditional dense busway product does not conduct heat and the cover plate does not contact the joint, so the thermal resistance is too large. The heat cannot be dissipated, causing the internal temperature of the connector part to be higher than that of other parts of the dense bus duct, posing a safety hazard.

Although Chinese Patent Application No. 201720400649.1 discloses "a busway connector with a heat-conducting plate", it can solve the problem that the temperature of the busway joint is too high, but because a heat-conducting plate is added, once the bolts are loosened, the thermal resistance will be larger. Although Chinese Patent Application No. 201921376840.2 discloses "a busway joint connection assembly with heat dissipation function", although the heat dissipation problem of the joint cover plate is solved, the heat dissipation plate provided makes the joint part higher than the main structure, which is not conducive to installation.
