Abstract
The utility model discloses a drawer cabinet of a low-voltage draw-out switchgear. The drawer cabinet of the low-voltage draw-out switchgear comprises a cabinet body (1), a disconnector (2), three mutual inductors (3), three wire-in ends (4) and three wire-out ends (5), wherein the disconnector (2), the three mutual inductors (3), the three wire-in ends (4) and the three wire-out ends (5) are arranged inside the cabinet body (1), the three wire-in ends (4) are respectively in electric connection with the corresponding mutual inductors (3) , the three mutual inductors (3) are in electric connection with corresponding wire-connecting ends of the disconnectr (2), the three wire-out ends (5) are in electric connection with other corresponding wire-connecting ends of the disconnectr (2), and the electric connection utilizes copper bars (6) as connecting materials. The drawer cabinet of the low-voltage draw-out switchgear is low in wire-connecting requirement, is convenient to overhaul, avoids short circuit of the drawer cabinet, and eliminates fire hidden dangers.
Description
Technical field
The utility model relates to low pressure draw out switchgear cabinet technical field, specifically is a kind of drawout cubicle of low pressure draw out switchgear cabinet.
Background technology
Low pressure draw out switchgear cabinet (being called for short GCS) is applicable to electric energy conversion, distribution and the control usefulness of power, distribution and motor control center, the capacitance compensation etc. of low-voltage distribution systems such as power plant, transformer station, petrochemical industry department, industrial enterprise, restaurant and skyscraper.
The drawout cubicle of present low pressure draw out switchgear cabinet generally comprises cabinet and circuit breaker, three instrument transformers, three ends of incoming cables and three leading-out terminals of being located in the cabinet; Three ends of incoming cables are electrically connected with corresponding instrument transformer respectively, corresponding terminals electrical connection on three instrument transformers and the circuit breaker, corresponding other terminals electrical connection on three leading-out terminals and the circuit breaker; This electrical connection all adopts cable to connect; This connected mode is suitable for rated current and is no more than 250A, if drawout cubicle is more than Unit 1.5, when rated current surpasses 250A; So not only increased material cost; And also raising greatly of butted line requirement, when drawout cubicle breaks down, maintenance has also been caused bigger puzzlement; If the drawout cubicle temperature is too high, can causes that the cable surface shell melts, and then cause the short circuit of drawout cubicle large tracts of land simultaneously, have fire safety evaluating hidden danger, thereby threaten user's life safety.
The utility model content
The technical problem that the utility model will solve is that the drawout cubicle that a kind of wiring requirement is low, overhaul conveniently, avoid the low pressure draw out switchgear cabinet of drawout cubicle short circuit, elimination disaster hidden-trouble is provided.
The technical scheme of the utility model is, a kind of drawout cubicle with low pressure draw out switchgear cabinet of following structure is provided, and comprises cabinet and circuit breaker, three instrument transformers, three ends of incoming cables and three leading-out terminals of being located in the cabinet; Three ends of incoming cables are electrically connected with corresponding instrument transformer respectively, corresponding terminals electrical connection on three instrument transformers and the circuit breaker, corresponding other terminals electrical connection on three leading-out terminals and the circuit breaker; Said electrical connection is copper bar and connects.
The two ends of said copper bar are equipped with bolt.
After adopting above structure, the utility model compared with prior art has the following advantages: at drawout cubicle more than Unit 1.5; When rated current surpasses 250A; The electrical connection of drawout cubicle adopts copper bar to be flexible coupling, and so not only can reduce material cost, and butted line requires also to reduce greatly; When even drawout cubicle breaks down, make maintenance also convenient; If the drawout cubicle temperature is too high, avoid causing the short circuit of drawout cubicle large tracts of land simultaneously, eliminate fire safety evaluating hidden danger, thereby guarantee user's life safety.
Description of drawings
Accompanying drawing is the schematic top plan view of drawout cubicle of the low pressure draw out switchgear cabinet of the utility model.
As shown in the figure: 1, cabinet, 2, circuit breaker, 3, instrument transformer, 4, leading-out terminal, 5, the end of incoming cables, 6, copper bar.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
As shown in the figure, the drawout cubicle of the low pressure draw out switchgear cabinet of the utility model comprises cabinet 1 and is located at circuit breaker 2 in the cabinet 1, three instrument transformers 3, three leading-out terminals 4 and three ends of incoming cables 5; Said three leading-out terminals 4 are electrically connected with corresponding instrument transformer 3 respectively, corresponding terminals electrical connection on said three instrument transformers 3 and the circuit breaker 2, corresponding other terminals electrical connection on said three ends of incoming cables 5 and the circuit breaker 2; Said electrical connection all adopts copper bar 6 to connect; Be that said three leading-out terminals 4 adopt copper bar 6 to connect with corresponding instrument transformer 3 respectively; Corresponding terminals adopt copper bar 6 to connect on said three instrument transformers 3 and the circuit breaker 2, corresponding other terminals employing copper bar 6 connections on said three ends of incoming cables 5 and the circuit breaker 2.
The two ends of said copper bar 6 are equipped with bolt, and this is bolted to by on the terminals of relay part.
