Embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
A kind of 40.5kV shown in Fig. 1~2 is greatly at a distance of fixed switching cabinet, including cabinet 16, and the inside of cabinet 16 is by two
The dividing plate 15 that block arranges in length and breadth is divided into four chambers, and four chambers are respectively cable vault 1, bus-bar room 2, breaker chamber 3, low pressure
Room 4；Dividing plate 15 is formed by the riveting of aluminizing zinc steel plate bending, makes each independently to separate between low-pressure chamber and each high pressure compartment.Bus
One end of main bus-bar 5 in room 2 is connected with porcelain bottle insulators 6, and the other end is connected with disconnecting switch 7；Between adjacent chamber
Porcelain bottle insulators are mounted on main bus-bar, in cabinet Internal faults arc, by accident be limited in compartment without to
Other chamber sprawlings.Main bus-bar 5 can use D types or O-shaped bus, with reference to epoxy resin sulfuration process, reach all insulation, improve
Cabinet internal electric field is distributed.
The one side of main bus-bar 5 is connected by disconnecting switch 7 with the No.1 current transformer 8 in cable vault 1, on the other hand
It is connected with the fuse 9 in breaker chamber 3；The output end of fuse 9 is provided with breaker 10；Breaker 10 can be with
Autoprotection function for monitoring sulfur hexafluoride breaker, the running status of open circuit is monitored at any time, when breaker emerged in operation is abnormal,
Device sends alarm, until locking, improves the reliability of equipment.Breaker can also be vacuum in light weight, stability is good
Breaker, therefore equipment compatibility is stronger.
The other end of fuse 9 is additionally provided with No. two current transformers 11；The output end of No. two current transformers 11 with it is low
Disconnecting switch in pressure chamber 4 is connected, and being accessed on the main bus-bar 5 on rear side of the disconnecting switch has copper bar 12；The other end of copper bar 12
It is provided with arrester 13；The rear end of arrester 13 is provided with voltage transformer 14.Disconnecting switch can disconnecting link with ground, install additional auxiliary
Switch, thoroughly solve plug and insert partially, depth is inadequate, not the same period, and contact resistance is big, overheats scaling loss and short trouble.
Cabinet 16 is armored withdraw type, and the insulation mode of cabinet 16 is the compound inslation of air and solid.In order to ensure
The top of operating personnel and the safety of switchgear, bus-bar room 2 and cable vault 1 is equipped with pressure relief device, when compartment interior occurs
During electric arc, cabinet air pressure inside rise, the special seal circle being installed on front door is closed cabinet door, the pressure release of top installing
Metallic plate is automatically switched on, and pressure and high-temperature gas is discharged, so as to improve the security reliability of product.
The present invention combines the theoretical research technology of 40.5kV switch cubicles and the acting characteristic of armored equipment, with various vacuum
The operation principle of breaker organically combines, and has the characteristics of product safety safeguard function is higher, and internal arcing is protected
