Abstract
A circuit breaker U-shaped bus bar structure mainly solves the problems of fast material heat emission, incapability of sufficiently using material heat and slow evaporation speed of an existing concentrator. The circuit breaker U-shaped bus bar structure comprises a bus bar seat (1) and bridge-shaped contacts (2), the section of the bus bar seat (1) is 'U'-shaped, and the bridge-shaped contacts (2) are clamped on two lateral walls of the bus bar seat (1). The circuit breaker U-shaped bus bar structure is characterized in that stripy gaps (3) are arranged on both of the two lateral walls of the bus bar seat (1). A circuit breaker U-shaped bus bar changes the structure of the bus bar seat, leads heat on the bus bar seat to be rapidly dissipated, and has fine heat dissipation performance.
Description
Technical field:
The utility model relates to a kind of circuit breaker bus row, belongs to a kind of circuit breaker U type bus row structure.
Background technology:
At present, circuit breaker bus row mainly is made up of bus row seat and bridge-shaped contact, bridge-shaped contact is made up of corresponding two row's contact chips, shell fragment and contact frame, contact chip two ends relative on the bridge-shaped contact form the jaw that can open or draw in, the cross section of bus row seat is " U " type, and an end of bridge-shaped contact is clamped in two sidewalls of bus row seat.Because the sidewall of bus row seat is an entity, in use the heat of Chan Shenging distribute slower, heat dispersion is poor.
The utility model content:
In order to overcome the deficiency of existing circuit breaker bus row heat dispersion difference, the utility model provides a kind of circuit breaker U type bus row structure, this circuit breaker U type bus row has changed the structure of bus row seat, makes that the heat on the bus row seat distributes perfect heat-dissipating soon.
The technical solution of the utility model is: a kind of circuit breaker U type bus row structure comprises bus row seat and bridge-shaped contact, the cross section of bus row seat is " U " type, bridge-shaped contact is clamped on two sidewalls of bus row seat, is equipped with strip crevice on two sidewalls of bus row seat.
Described strip crevice is in the intersection of adjacent bridge-shaped contact.
The utlity model has following beneficial effect: owing to take such scheme, two sidewalls of bus row seat are provided with the external surface area that strip crevice has increased bus row seat, increase the heat-dissipating space and the area of circuit breaker bus row seat, reduced the temperature rise on the circuit breaker major loop effectively, it is very fast to make that heat on the bus row seat distributes, perfect heat-dissipating.On the other hand, the copper scale that mills out from circuit breaker major loop busbar can utilize again.So not only improved circuit breaker temperature rise performance, also saved valuable copper raw material metal and reduced product weight.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is vertical views of Fig. 1.
1-bus row seat among the figure, 2-bridge-shaped contact, 3-strip crevice.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with shown in Figure 2, a kind of circuit breaker U type bus row structure comprises bus row seat 1 and bridge-shaped contact 2, the cross section of bus row seat 1 is " U " type, and bridge-shaped contact 2 is clamped on two sidewalls of bus row seat 1, is equipped with strip crevice 3 on two sidewalls of bus row seat 1.Two sidewalls of bus row seat 1 are provided with the external surface area that strip crevice 3 has increased bus row seat 1, increase the heat-dissipating space and the area of circuit breaker bus row seat 1, reduced the temperature rise on the circuit breaker major loop effectively, it is very fast to make that heat on the bus row seat 1 distributes, perfect heat-dissipating.On the other hand, the copper scale that mills out from circuit breaker major loop busbar can utilize again, has so not only improved circuit breaker temperature rise performance, has also saved valuable copper raw material metal and has reduced product weight.
By shown in Figure 1, described strip crevice 3 is in the intersection of adjacent bridge-shaped contact 2.Avoid bridge-shaped contact 2 that strip crevice 3 is sheltered from, influence radiating effect.
Claims (2)
1. a circuit breaker U type bus is arranged structure, comprise bus row seat (1) and bridge-shaped contact (2), the cross section of bus row's seat (1) is " U " type, bridge-shaped contact (2) is clamped on two sidewalls of bus row's seat (1), it is characterized in that: be equipped with strip crevice (3) on two sidewalls of bus row's seat (1).
2. a kind of circuit breaker U type bus row structure according to claim 1, it is characterized in that: described strip crevice (3) is in the intersection of adjacent bridge-shaped contact (2).
