Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the end view of Fig. 1.
Embodiment
Referring to figs. 1 through Fig. 2, this embodiment by the following technical solutions: the outdoor intelligent vacuum circuit breaker of a kind of measurement and relay protection one, comprises operating grip 1, isolation main shaft 2, circuit breaker manual deciliter handle 3, energy accumulation handle for circuit breaker 4, deciliter mark 5, connection plug 6, terminal block 7, circuit breaker pillar 8, measurement and relay protection integrated device 9, isolation blade 10, insulator 11, insulated tension pole 12 and isolating frame 13, operating grip 1 is connected with casing 14 by isolation main shaft 2, and casing 14 side is provided with circuit breaker manual deciliter handle 3, energy accumulation handle for circuit breaker 4, deciliter mark 5, connection plug 6, casing 14 is vertically provided with circuit breaker pillar 8, circuit breaker pillar 8 top is provided with terminal block 7, the circuit breaker pillar 8 being positioned at casing 14 two ends is connected with measurement and relay protection integrated device 9 by Connection Block, measurement and relay protection integrated device 9 is also connected with the binding post on insulator 11 by isolation blade 10, and isolation blade 10 is also connected with isolating frame 13 by insulated tension pole 12, current transformer and metering coil is provided with in described measurement and relay protection integrated device 9.
It should be noted that the primary winding of the current transformer in described measurement and relay protection integrated device 9 connects power positive cathode, the secondary coil of current transformer connects metering coil.
In addition, the current transformer in described measurement and relay protection integrated device 9 is electrically connected with circuit breaker pillar 8.
This embodiment circuit breaker adopts three-phase column support type structure, have break performance reliable and stable, without burning and explosion hazard, freedom from repairs, volume the feature such as little, lightweight and long service life.Circuit breaker adopts full-closed structure, good seal performance, contributes to improving moistureproof, anti-condensation performance, is specially adapted to severe cold or humid area use.Three-phase pillar and current transformer adopt the outdoor epoxy resin solids insulation of import, or adopt indoor epoxy resin outsourcing organic silicon rubber solid insulation; There is high-low temperature resistant, UV resistant, the feature such as ageing-resistant.Operating mechanism adopts small size spring operating mechanism, and energy storage motor power is little, and divide-shut brake energy consumption is low.Mechanism driving adopts direct acting transmission means, and amount of parts is few, and reliability is high.Operating mechanism is placed in the mechanism case of sealing, solves the problem of operating mechanism corrosion, improves the reliability of mechanism.Circuit breaker point, closing operation can adopt manually or electric operating and remote control operation.
