Description
Technical field
The utility model relates to a kind of power switchgear, particularly a kind of indoor metal armoring draw out switchgear.
Background technology
At present, as the indoor complete power distribution equipment of accepting and distribute electric energy, fixed switchgear is mainly used in being subjected to electricity, sending electricity and motor of electric substation in power plant, industrial and mining enterprises' distribution and the electric power system, the control of transformer and the protection.Existing fixed formula switchgear is the box stationary structure, and the ubiquity volume is big, the big shortcoming in occupation of land space, does not especially have pressure relief device between each isolation ward, in case internal fault, the personal safety that endangers the operations staff easily take place.Meanwhile because the layout of fixed switchgear is unreasonable, not only maintenance difficulty, and lack enough safety guarantee and safety measure, both be unfavorable for the safe operation of equipment and maintenance fast, also can't realize the quick assembling and the debugging of equipment, and lack operability.
The utility model content
The purpose of this utility model is to improve the shortcoming of prior art and product, and provide a kind of indoor metal armoring draw out switchgear, this indoor metal armoring draw out switchgear novel structure, volume is little, both convenient assembling fast, easy access again, handling safety reliably satisfies " five is anti-" requirement fully simultaneously.
For achieving the above object, the utility model provides a kind of indoor metal armoring draw out switchgear, described indoor metal armoring draw out switchgear comprises the armouring cabinet, be provided with bus-bar room, circuit breaker cart chamber, cable vault and relay control room in the described armouring cabinet, described relay control room is positioned at the top of armouring cabinet front portion, described circuit breaker cart chamber is positioned at below, described relay control room, described bus-bar room is positioned at rear, described circuit breaker cart chamber, and described cable vault is positioned at described bus-bar room below; Described circuit breaker cart is provided with circuit breaker cart in the chamber, this circuit breaker cart is provided with heater, be provided with valve between described bus-bar room and circuit breaker cart chamber, the fixed contact box is installed on this valve, the static contact head device in this fixed contact box is switch with described circuit breaker cart and cooperates; The cabinet wall of top, described circuit breaker cart chamber is provided with secondary plug, and this secondary plug is connected with described circuit breaker cart.
Further, in order to increase the independence fail safe of each chamber, can stop the extension of electric arc effectively again, thereby issuable fault is limited in the minimum scope, adopt metal partion (metp) to isolate between described bus-bar room, circuit breaker cart chamber, cable vault and the relay control room.
Further, in order to ensure the safety of operating personnel and switch cubicle, in described bus-bar room, circuit breaker cart chamber and the cable vault pressure relief device is installed all, like this when circuit breaker or bus generation internal fault, the pressure relief device at top is opened automatically, release pressure and drainage gas.
Further, in order to make circuit breaker cart more convenient to operate, only make it that its breaker closing, separating brake could move when work or test position, on the indoor both sides cabinet wall of described circuit breaker cart track is installed, described circuit breaker cart is installed on the described track by turbine, worm screw.
Further, moving contact on the described secondary plug links to each other with circuit breaker cart by the nylon bellows, the purpose of doing like this be to have only when circuit breaker cart the test, open position, just can plug or extract secondary plug, when the short-circuiting device handcart is in work because the effect of interlocking device, secondary plug is locked, can't extract, thereby guarantee user's safety.
Further, in order the user can be entered in the cabinet equipment is installed or to safeguard that the base plate of described circuit breaker cart chamber is withdrawable horizontal baffle.
The utility model is compared with existing product, has following actively useful effect:
1, the utlity model has reliable interlock, satisfy " five is anti-" requirement fully, guarantee operating personnel's personal safety and device security.
(1) on control room's door suggestive button or change over switch are housed, to prevent that mistake from closing, mistake is divided circuit breaker.
(2) circuit breaker cart is when " test " or " work " position, and circuit breaker just can carry out the branch closing operation, and behind breaker closing, handcart can't move, and prevents on-load push-and-pull circuit breaker cart.
(3) only when earthed switch is in the separating brake position, circuit breaker cart could move to " work " position from " test/disconnection " position; Only when circuit breaker cart is in " test/disconnection " position, earthed switch just can carry out sub-switching operation (earthed switch can display unit with voltage).Realized preventing charged mistake splice grafting ground switch like this and prevented to close when earthed switch is in make position closing short-circuiting device.
When (4) earthed switch was in the separating brake position, Xiamen and back door all can't be opened, and had prevented the mistakenly entering into charged compartment.
(5) circuit breaker cart is really when " test " or " work " position, and when not controlling voltage, and only manual separating brake can not close a floodgate.
(6) circuit breaker cart is when " work " position, and secondary plug is locked can not be extracted.
2, this switchgear has complete metal armouring and full-closed structure, independently separates separately between low-pressure chamber and each the high pressure compartment
3, volume is little, both convenient assembling fast, easy access again.
4, stable performance, rational in infrastructure, easy to use, applied range.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
