Abstract
Disclosed is a fixed type metal enclosing switch device, comprising a cabinet body. The cabinet body is internally provided with a master switch chamber, a bus-bar chamber, a cable chamber, and an instrument chamber, wherein the cable chamber is located behind the master switch chamber; the bus-bar chamber is arranged above the cable chamber; the instrument chamber is arranged upon the top of the master switch chamber; the master switch chamber is internally provided with a pressure release channel; the master switch chamber is internally provided with a vacuum circuit breaker; a lower binding post of the vacuum circuit breaker is connected with a current transformer; the current transformer is connected with the binding post of a lower isolation switch; and the upper binding post of the vacuum circuit breaker is connected with the binding post of an upper isolation switch. With this structure, the master switch chamber, the bus bar chamber, the cable chamber, and the instrument chamber inside the cabinet body are reasonably established, thereby allowing double face maintenance and debugging, with less land occupation area and convenient operation. The design of the pressure release channel in the master switch chamber allows the pressure to be released through venting when the arc occurs, thereby ensuring the normal operation of the device and substantially improving the security and reliability of the device.
Description
Technical field
The utility model relates to the switchgear that a kind of electric power is used, and specifically is employed in order to accept and the fixed metal enclosed switchgear that distributes electric energy to use in a kind of electric power system.
Background technology
Fixed metal enclosed switchgear at home and abroad application surface is very wide; In electric power system at present; Existing fixed formula metal enclosed switchgear mainly is concatenated into the main electrical scheme loop by the requirement of main electrical scheme with isolating switch, circuit breaker, current transformer, with the electric energy inlet highway or by bus electric energy is exported, and dividing with arrangement of cabinet functional unit is unreasonable; Not only maintenance difficulty, and lack enough safety guarantee and safety measure; In the internal structure of fixed metal enclosed switchgear; All establish two groups of isolating switches and satisfy control, the requirement of isolation safely with many group current transformers in the circuit breaker both sides; Do not consider the reasonable construction between main switch chamber, bus-bar room, cable vault, the control room in the cabinet more; Cause not only that the cabinet size is big, floor space is big, and very inconvenience of operation.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model purpose is to provide a kind of compact conformation, the little and easy to operate fixed metal enclosed switchgear of cabinet size.
To achieve these goals, the technical scheme of the utility model employing is:
Fixed metal enclosed switchgear includes cabinet, is provided with main switch chamber, bus-bar room, cable vault, control room in the cabinet; The cable vault is positioned at after the main switch chamber; Bus-bar room is positioned at the top, cable vault, and the control room is positioned at top, main switch chamber, the indoor pressure relief channels that is provided with of said main switch; The indoor vacuum circuit-breaker that is provided with of said main switch, lower joint of vacuum circuit-breaker is connected with current transformer, and current transformer is connected with the binding post of following isolating switch, and the binding post of vacuum circuit-breaker upper connecting terminal and last isolating switch joins.
Indoor hand-power actuating and the interlocking device of being provided with of said main switch.
Bus in the said bus-bar room is the arrangement of article shape and is connected with last isolating switch binding post.
The beneficial effect of the utility model: owing to adopt above-mentioned structure, main switch chamber, bus-bar room, cable vault, control room in the cabinet are reasonably made up, not only can two-sided maintenance and debugging, and also floor space is little, is convenient to operation; The design of main switch room pressure release channel, when electric arc took place, gas can have been guaranteed the operate as normal of equipment through exhaust through pressure is discharged, and has improved the security reliability of equipment greatly.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to specify.
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, main switch chamber; 2, bus-bar room; 3, cable vault; 4, control room; 5, cabinet; 6, vacuum circuit-breaker; 7, bus; 8, hand-power actuating and interlocking device; 9, current transformer; 10, following isolating switch; 11, go up isolating switch; 12, pressure relief channels.
Embodiment
As shown in Figure 1, fixed metal enclosed switchgear, it comprises cabinet 5; Be provided with main switch chamber 1, bus-bar room 2, cable vault 3, control room 4 in the cabinet 5; Cable vault 3 is positioned at after the branch main switch chamber 1, and bus-bar room 2 is positioned at 3 tops, cable vault, and control room 4 is positioned at main switch chamber l top.Adopt steel plate to separate between main switch chamber 1, bus-bar room 2, cable vault 3, the control room 4 and switch cubicle is two-sided opens, be convenient to carry out two-sided maintenance.The transmission that is positioned at the vacuum circuit-breaker 6 of main switch chamber 1 is connected by hand-power actuating and interlocking device 8; Vacuum circuit-breaker 6 lower joints is connected with current transformer 9, and current transformer 9 is connected with the binding post of following isolating switch l0, and the binding post of vacuum circuit-breaker 6 upper connecting terminals and last isolating switch ll joins; Main switch chamber 1 is provided with pressure relief channels 12; If when internal arc took place, gas can discharge pressure through the exhaust passage, thereby has guaranteed the safety of equipment.In order to reduce the height of cabinet 5, the bus 7 in the bus-bar room 2 is the arrangement of article shape and is connected with last isolating switch 11 binding posts, and the supporting insulators in the cable vault 3 are provided with monitoring arrangement.Cabinet 5 is two-sided maintenance type structure, and the secondary component of relay is mainly overhauled in the front, safeguards operating mechanism, mechanical interlocking and running part, safeguards main bus bar and cable termination at the back and in main switch chamber and cable vault, illuminating lamp is housed.
The above is the preferred implementation of the utility model, can not limit the interest field of the utility model certainly with this.Should be pointed out that for those skilled in the art, the technical scheme of the utility model is made amendment or is equal to replacement, do not break away from the protection range of the utility model.
