Embodiment Construction

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] like figure 1 , figure 2 A busbar device of a low-voltage power distribution system shown, which includes a low-voltage circuit breaker 1, a switch bracket 2, a terminal 3, a busbar 4, a busbar bracket 6, and a contact 7, and the low-voltage circuit breaker 1 passes through the switch bracket 2. For fixing, one end of the terminal 3 is connected to the low-voltage circuit breaker 1 through screws, and the other end is connected to the contact 7, which is connected to the busbar 4, and the busbar 4 is fixed outside the low-voltage circuit breaker 1 by the busbar bracket 6.

[0016] There are three bus bars 4, and each bus bar 4 is connected with contacts 7 respectively. The contacts 7 are connected to each other through the row wires 8 and are connected to the terminal 3. The bus bar 4 is connected to the low-voltage circuit breaker. 1 a...

Abstract

A busbar device for a low-voltage power distribution system, which includes a low-voltage circuit breaker, a switch bracket, a terminal, a busbar, a busbar support, a busbar bracket, and contacts. The low-voltage circuit breaker is fixed by a switch bracket, and one end of the terminal post is connected to the The low-voltage circuit breaker is connected, and the other end is connected to the contact, and the contact is connected to the bus bar, and the bus bar is fixed outside the low-voltage circuit breaker by the bus bar bracket. The busbar is a circular hollow tubular line. The contact part between the contact and the bus bar is a semi-circular arc structure. The busbar adopts a circular tubular busbar, which has the advantages of uniform electric field and current distribution and good dynamic stability. Better saving of busbar materials, and easy to realize the standardized production of the whole system; the contacts are arc-shaped, with large contact area and small resistance, and the switch bracket is directly installed on the tubular busbar without supporting busbars, which greatly reduces the amount of copper used .

Description

technical field [0001] The invention relates to the field of low-voltage power transmission and distribution systems of power systems, in particular to a busbar device of a low-voltage power distribution system. Background technique [0002] The busbars of conventional low-voltage power distribution systems are generally rectangular busbars, which are further divided into main busbars and branch busbars. The branch busbar connects the low-voltage switch with the main busbar. The disadvantage is that it occupies a large space, uses a large amount of busbars, takes time and labor to process and install the busbars, is difficult to install and maintain, and has high costs. [0003] Low-voltage drawer cabinets (such as MNS, GCS, GCK, etc.) also use rectangular busbars. The advantage is that the replacement of the drawer is convenient and fast; Large, difficult to dissipate heat, and high failure rate. [0004] The power distribution system similar to the Wiener busbar adopts ...
