Abstract
The utility model relates to indoor metal armored draw-out switch equipment, which consists of two parts, namely a cabinet body and a handcart. The cabinet body is divided into a bus chamber, a circuit breaker handcart chamber, a cable chamber and a low-voltage electric instrument chamber; a main bus in the bus chamber is connected with a fixed contact of an isolating switch; a movable contact of the isolating switch is connected with a circuit breaker; primarily, the isolating switch is arranged on an epoxy resin insulating plate of which the surface is immersed with a layer of insulating varnish; and the indoor metal armored draw-out switch equipment has the advantages of high insulation level and the like, and is suitable for a high-voltage power system of 24kV voltage level.
Description
Technical field
The utility model relates to a kind of switchgear, particularly about a kind of indoor metal armoring draw out switchgear.
Background technology
Indoor metal armoring draw out switchgear is used for electric power system as accepting and distributing electric energy and circuit is carried out control, protection and monitoring.As the patent No. is the indoor metal armoring draw out switchgear of ZL2005200453597, mainly form by cabinet and the handcart two parts that can extract out, cabinet is made of shell and dividing plate, and is separated to form breaker compartment, bus cell, cable connection compartment, low-voltage compartment four parts.Main weak point is that isolating switch is installed on the corrosion resistant plate, and its fixed contact, moving contact are lacked to the creepage distance of corrosion resistant plate, and the class of insulation is low, can only be suitable for the electric power system of 12KV electric pressure, and can not be suitable for the high-voltage electric power system of 24KV electric pressure.
Summary of the invention
The purpose of this utility model is the deficiency that exists at prior art, and a kind of class of insulation height is provided, and is suitable for the indoor metal armoring draw out switchgear of 24KV electric pressure.
The technical solution of the utility model is made up of cabinet and handcart two parts, cabinet is separated to form bus-bar room, circuit breaker cart chamber, cable vault and low-voltage electrical apparatus control room, main bus bar in the bus-bar room is connected with static contact isolation switch, the isolating switch moving contact is connected with circuit breaker, mainly is that isolating switch is installed on the surface and is soaked with on the epoxy resins insulation plate of one deck insulating varnish.
In above technical scheme, be provided with dividing plate at isolating switch housing mouth, this dividing plate is installed in the inwall of circuit breaker cart chamber, links with circuit breaker cart.
The utility model has the advantages that isolating switch is installed on the insulation board, its class of insulation height can be applicable to the high-voltage electric power system of 24KV electric pressure.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Indoor metal armoring draw out switchgear as shown in Figure 1, form by cabinet 1 and handcart two parts, cabinet 1 is separated to form bus-bar room A, circuit breaker cart chamber B, the C of cable vault and the D of low-voltage electrical apparatus control room, main bus bar 4 among the bus-bar room A is connected with static contact isolation switch 5 by branch bar 2, the isolating switch moving contact is connected with a contact of circuit breaker 16, and another contact of circuit breaker 16 is connected with cable 9 by connection bus 18.Current transformer 7, transducer, earthed switch 8 and lightning arrester 10 are installed on the connection bus 18.Circuit breaker 16 adopts solid sealing type vacuum circuit breaker, is installed on the circuit breaker cart 15, and circuit breaker cart 15 is installed in the B of circuit breaker cart chamber by withdrawable horizontal baffle 17.Main bus bar 4 is installed on the insulating mounting plate by bus cover 3.Isolating switch 6 is installed on the surface and is soaked with on the epoxy resins insulation plate 12 of one deck insulating varnish, improves insulating properties.Be provided with dividing plate 13 at isolating switch 6 housing mouths, this dividing plate 13 is installed in the inwall of circuit breaker cart chamber B, with circuit breaker cart 15 interlocks, when circuit breaker cart 15 opens a sluice gate to operate, dividing plate 13 auto-closings, when circuit breaker cart 15 did to close a floodgate operation, dividing plate 13 was opened automatically.Earth bus 11 is installed on the base plate 14 of cabinet 1, is guaranteed the equipment reliable ground.
