Abstract
A circuit breaker is provided. A current transformer cannot be installed on a porcelain-column-type circuit breaker directly, and the earthquake-proof performance of the porcelain-column-type circuit breaker is poor. The circuit breaker in the utility model comprises a pair of outgoing line porcelain sleeves (3). An upper grading ring (2) is arranged on the top end of each outgoing line porcelain sleeve; each upper grading ring is connected with a wiring terminal (1); each outgoing line porcelain sleeve is connected with a lower grading ring (4); the outgoing line porcelain sleeves are connected with a housing (11); a current transformer (12) is arranged at the connection place between the outgoing line porcelain sleeve and the housing; the housing is internally provided with a bidirectional longitudinally-blowing arc extinguish chamber (8); the arc extinguish chamber is connected with a bus A arranged in the left-side outgoing line porcelain sleeve; a stationary contact (9) is arranged at the right side of the arc extinguish chamber; the stationary contact is connected with a basin-type insulator (10); the basin-type insulator is connected with the housing; and the stationary contact is connected with a bus B (13) arranged in the right-side outgoing line porcelain sleeve. The circuit breaker is used for circuit breaking.
Description
technical field:
the utility model relates to a kind of circuit breaker.
background technology:
existing sulfur hexafluoride breaker adopts porcelain knob breaker more, and current transformer can not be directly installed on porcelain knob breaker, need install separately; Because porcelain knob breaker center of gravity is high, its poor seismic behavior.
utility model content:
the purpose of this utility model is to provide a kind of circuit breaker.
above-mentioned object realizes by following technical scheme:
a kind of circuit breaker, its composition comprises: a pair of outgoing line porcelain bushing pipe, upper grading ring is arranged on the top of described outgoing line porcelain bushing pipe, described upper grading ring is connected with binding post, described outgoing line porcelain bushing pipe is connected with lower uniform pressure ring, described outgoing line porcelain bushing pipe is connected with housing, at described outgoing line porcelain bushing pipe and described housing junction, current transformer is installed, the two-way vertical formula arc control device that blow are installed in described housing, described arc control device are connected with the bus A being arranged in the outgoing line porcelain bushing pipe of left side, described arc control device right side has fixed contact, described fixed contact is connected with disc insulator, described disc insulator is connected with described housing, described fixed contact is connected with the bus B being arranged in the outgoing line porcelain bushing pipe of right side.
described circuit breaker, described housing left side is provided with crank arm box, and described crank arm box is connected with mechanism case, and described housing is connected with pedestal, and described pedestal adopts damping steel structure pedestal.
beneficial effect:
1. the utility model is fitted together tripper and current transformer, compact conformation, and antiseismic and antifouling ability is strong,
2. the utility model is given full play to the arc blow-out effect of air-flow, and arc control device volume is little, simple in structure, drop-out current is large, the arcing time is short, cut-offs electric capacity or inductive current without restriking or without resume combustion.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present utility model.
embodiment:
embodiment 1:
a kind of circuit breaker, its composition comprises: a pair of outgoing line porcelain bushing pipe 3, upper grading ring 2 is arranged on the top of described outgoing line porcelain bushing pipe, described upper grading ring is connected with binding post 1, described outgoing line porcelain bushing pipe is connected with lower uniform pressure ring 4, described outgoing line porcelain bushing pipe is connected with housing 11, at described outgoing line porcelain bushing pipe and described housing junction, current transformer 12 is installed, the two-way vertical formula arc control device 8 that blow are installed in described housing, described arc control device are connected with the bus A being arranged in the outgoing line porcelain bushing pipe of left side, described arc control device right side has fixed contact 9, described fixed contact is connected with disc insulator 10, described disc insulator is connected with described housing, described fixed contact be arranged on the bus B in the outgoing line porcelain bushing pipe of right side, piece number: 13 connect.
embodiment 2:
according to the circuit breaker described in embodiment 1, described housing left side is provided with crank arm box 5, and described crank arm box is connected with mechanism case 6, and described housing is connected with pedestal 7, and described pedestal adopts damping steel structure pedestal.
embodiment 3:
described circuit breaker, adopt construction steel structure pedestal, pedestal is fixed on original structure, original structure top is by implanting chemical anchor bolts junction steel plate or welding lower steel plate, secondary mechanism's beam lower end welding upper steel plate, in the middle of upper steel plate and lower steel plate, place beam, upper steel plate and lower steel plate are bolted, and shock absorbing ring is installed on bolt.By the beam and the shock absorbing ring that add between upper girder steel and lower girder steel, avoid traditional pedestal junction steel plate position to place beam, beam aging problem in welding process, effectively solve simultaneously sound high by the steel construction coefficient of conductivity, there is overhead speaker phenomenon.
Claims (2)
1. a circuit breaker, its composition comprises: a pair of outgoing line porcelain bushing pipe, it is characterized in that: upper grading ring is arranged on the top of described outgoing line porcelain bushing pipe, described upper grading ring is connected with binding post, described outgoing line porcelain bushing pipe is connected with lower uniform pressure ring, described outgoing line porcelain bushing pipe is connected with housing, at described outgoing line porcelain bushing pipe and described housing junction, current transformer is installed, the two-way vertical formula arc control device that blow are installed in described housing, described arc control device are connected with the bus A being arranged in the outgoing line porcelain bushing pipe of left side, described arc control device right side has fixed contact, described fixed contact is connected with disc insulator, described disc insulator is connected with described housing, described fixed contact is connected with the bus B being arranged in the outgoing line porcelain bushing pipe of right side.
2. circuit breaker according to claim 1, is characterized in that: described housing left side is provided with crank arm box, and described crank arm box is connected with mechanism case, and described housing is connected with pedestal, and described pedestal adopts damping steel structure pedestal.
