Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the present invention will be further described.
As shown in Figures 1 to 5, a kind of compact drawing type high voltage switch cabinet, including main bus-bar room, cable vault and open circuit Device room, wherein cable vault and breaker chamber are arranged on the lower section of main bus-bar room, between main bus-bar room and cable vault, breaker chamber by Insulating barrier I9 separates, and is separated between cable vault and breaker chamber by insulating barrier II2, insulating barrier III11, insulating barrier II2 is active clapboard.
II2 points of insulation board is two boards, plate and plate synchronization action, and two boards break in the mechanism of tape spool with pull-out type The handcart of road device 10 realizes linkage, and when breaker 10 is in testing position (such as Fig. 1), they are as plate washer shelves in breaker chamber Between cable vault;When breaker is walked from testing position toward operating position (such as Fig. 2), linkage mechanism action revolves plate washer It goes between two groups of static contacts.
In main bus-bar room in parallelly be equipped with the main busbar 6 of three-phase bus, each main busbar 6 be installed on insulation column 7 and absolutely In edge casing 4, insulating sleeve 4 is fixed at the both sides of main bus-bar room and insulation column 7 is fixed at the upper end of main bus-bar room.
Branch bar 8 is connected on each main bus-bar row 6 and the another of branch bar 8 is terminated on insulation column 3, insulation Pillar 3 is arranged in cable vault, and the lower section of insulation column 3 in cable vault is equipped with three current transformers 1, is grounded and opens successively Close 12, insulation column 3 close to one end of breaker chamber be equipped in three parallel static contacts 16 and three current transformers 1 are close One upper end of breaker chamber is respectively equipped with three static contacts 16, and three current transformers 1 are fixed on by support plate in cable vault, and three Platform current transformer 1 is connected to earthing switch 12 by branch row 18 respectively close to a lower end of breaker chamber, and earthing switch 12 divides Cable 13 is not connect and finally collects the bottom for being fixed on cable vault by cable 13, and the bottom space of cable vault can fill zero sequence electricity Current transformer 19, can be with zinc oxide surge arresters 20 and voltage transformer.
Drawout breaker is placed with by fixed bottom plate 15 and circuit breaker/load switch pillar beam 14 in breaker chamber 10, one side upper end, the lower end of drawout breaker 10 are in parallelly to set there are three moving contact 17 respectively, and breaker 10 is in work During state three moving contacts 17 in upper end be inserted into the static contact 16 of insulation column 3, three in lower end it is dynamic Contact 17 is inserted into the static contact 16 of current transformer 1.
The invention discloses a kind of compact drawing type high voltage switch cabinets, it is mainly by metal cabinet shell and associated enclosure Component composition, be divided into three rooms in metal cabinet, be main bus-bar room, branch bar and cable vault respectively from top to bottom and disconnected Road device room, main bus-bar room, branch bar and cable vault and breaker chamber are equipped with the main busbar of three-phase bus, branch bar, insulation Pillar, current transformer, drawout breaker (or fuse), earthing switch and cable.The present invention maximum the characteristics of be exactly Box sizes are compact, safeguarded before being operated before preceding wiring, and main bus-bar room, breaker chamber and three, cable vault individually into room, are improved anti- Shield, breaker is pull-out type, convenient for safeguarding.
, can be mounted against a wall behind cabinet the invention belongs to a kind of compact drawing type high voltage switch cabinet, it is connect before realizing Line, preceding operation and preceding maintenance, width are 1.4~1.8m, and depth is 1.6~2m, is highly 2.3~3.2m, saves passage after cabinet, Depth has also saved 1m or so than existing withdraw-type cabinet.Breaker of the present invention by it is straight made into it is straight after again it is left into or it is right Into, the depth for reducing cabinet is equivalent to, moreover, by the use of mutual inductor and insulator as the static contact of breaker, reduce it Its equipment as intermediate link, meanwhile, by the use of insulating barrier as electric insulation, cause the facility for both having reached mobile unit Property reached again entire babinet size it is small the advantages of, and made into safeguard before operating before preceding wiring, made the arrangement ruler of equipment Very little also smaller saves significant cost, reserved safe distance is needed to reduce before cabinet very much, has saved installation device location Space, be worth realize commercialization.
