Description

Technical Field

[0001] The utility model relates to the technical field of tap-off boxes, in particular to a connection tap-off box for a compact busbar trunking system. Background Art

[0002] The original busbar tap-off unit uses the plug-in method of a tap-off box to connect the current of the main trunk busbar to the branch line. Its pins are of the snap-on type. The U-shaped pins are directly plugged into the phase conductor of the busbar, and their contact surface is a line surface. At the same time, when the pins are plugged and matched with the phase conductor of the busbar trunking system, a certain clamping force is required to ensure close contact and conduction between the pins and the phase conductor. Such a connection method has many drawbacks. Insufficient force on the pin copper sheet may affect the current-carrying capacity of the socket row. Uneven force will cause the temperature rise at the contact part between the pin and the main line unit to be too high, and poor contact during the installation process, etc., which are likely to cause accidents. At the same time, when a fault occurs in the busbar tap-off unit (branch box), maintenance personnel need to first conduct on-site inspections and then repairs, with low efficiency and heavy workload; the installation range of the busbar tap-off unit (branch box) is wide and the heights are different, making the maintenance work difficult.

[0003] For example, the utility model patent with the patent number 202120353973.9 discloses a connection tap-off box for a compact busbar trunking system. It sucks the outside air into the inside of the branch box through a cooling fan to play a role in heat dissipation. The driving motor is started to make the lead screw rotate, driving the threaded block to move up and down, and making the horizontal pipe move up and down. The wind is discharged through the branch pipe, which can make the wind fully contact the electronic components in the branch box, thereby improving the heat dissipation effect. However, only using a cooling fan for ventilation and heat dissipation is difficult to ensure the heat dissipation effect. In view of this, a connection tap-off box for a compact busbar trunking system is proposed. Summary of the Utility Model
