Abstract
The utility model discloses a switch cabinet. A cabinet body is divided into different areas by galvanized steel sheets. The switch cabinet comprises a bus chamber, an instrument chamber and a wire outlet chamber. The switch cabinet achieves the function of isolating a main electrified bus and is convenient to overhaul; a vacuum circuit breaker is easily replaced; and other adjacent parts are prevented from being influenced by fault parts. Separated voltage-relief channels are respectively arranged in the instrument chamber and the bus chamber. The cabinet body is vacuum insulated from air; and the vacuum circuit breakers in various model numbers can be assembled in the wire outlet chamber. By using the technical scheme of the utility model, an installation structure in the cabinet and the connection of the wire are simplified; and the switch cabinet has a compact structure, safe and reliable application and a better protecting function.

Technical field
The utility model relates to indoor switchgear field, is specifically related to a kind of switch cubicle that is widely used in the power supplying and distributing equipment.
Background technology
The indoor switchgear of three-phase alternating current is widely used in industry and civilian for distribution, as occasions such as city neighborhood distribution, compact secondary, switching station, box-type substation, industrial and mining enterprises, market, subway, wind power generation, hospital, railways.
Existing common ring main unit can only assemble pressure-operated load switch, is used for the less common distribution load of capacity, even when adopting isolating switch and vacuum circuit-breaker to cooperate, five anti-interlockings also just perform practically no function.The degree of protection of cabinet is lower, and is bulky, when cooperating with vacuum circuit-breaker, can only adopt electric-magnetic lock and electrical interlock mode to realize interlocking, and lower grade of anti-misoperation, can not satisfy than the requirement of high breaking capacity and electric current etc.
The utility model content
The utility model has overcome the deficiencies in the prior art, and a kind of compact conformation, safe and reliable switch cubicle are provided.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of switch cubicle, comprise cabinet, the switchgear that is provided with in the cabinet comprises isolating switch, vacuum circuit-breaker summation current transformer, bus-bar room, control room, outlet chamber will be divided into by dividing plate in the cabinet, each switching component is positioned at respective chambers, avoid trouble location to have influence on other switching components, be convenient to Maintenance and Repair and change vacuum circuit-breaker.
Further technical scheme is in the above-mentioned bus-bar room bushing and isolating switch to be installed, master's contact knife and ground connection piece were harmonious when isolating switch separated, outlet side joint ground can conveniently overhaul the outlet side apparatus under the charged situation of main bus bar, improved the reliability of power supply.
Further technical scheme is the above-mentioned indoor installation vacuum circuit-breaker of outlet summation current transformer, electrified sensor, lightning arrester.
Further technical scheme is to be provided with pressure release passage in the above-mentioned control room.
Further technical scheme is to be provided with pressure release passage in the above-mentioned bus-bar room.
Further technical scheme is that above-mentioned dividing plate is a galvanized steel plain sheet again.
Also further technical scheme is that above-mentioned cabinet is the air insulation switch cubicle.
The technical program can also be that above-mentioned vacuum circuit-breaker is provided with the vacuum interrupter chamber door, the outlet chamber is provided with outlet chamber door, described isolating switch, vacuum circuit-breaker, vacuum interrupter chamber door, outlet chamber Men Douyu operation locking mechanism connect, operation locking mechanism adopts gear-driven form to realize breaker chamber door and outlet chamber door mechanical interlocking, only just can open breaker chamber door and outlet chamber door when isolating switch and vacuum circuit-breaker separate.
The technical program further is that above-mentioned isolating switch is a miniaturization DGN-12 isolating switch again.
Compared with prior art, the beneficial effects of the utility model are:
Technical solutions of the utility model are mainly used in the 3-12kV switch cubicle, this switch cubicle is divided into zones of different by galvanized steel plain sheet with cabinet, reached the effect of isolating charged main bus bar, and maintenance is convenient, vacuum circuit-breaker is changed easily, avoids trouble location to have influence on other adjacent components.All be provided with independently pressure release passage in control room and the bus-bar room, cabinet is an air insulation, the indoor vacuum circuit-breaker that assembles various models of outlet.Simplified being connected of mounting structure and line in the cabinet by the technical solution of the utility model, compact conformation, safe and reliable has good safeguard function.
