Abstract

The invention belongs to the field of high-voltage electric device sets and in particular relates to a high-voltage switch cabinet. The high-voltage switch cabinet comprises a cabinet shell, a bus room, a circuit breaker handcart room, a cable room and a relay meter cabinet, wherein the bus room is provided with a bus, a bus sleeve covers the bus, the circuit breaker handcart room is provided with a circuit breaker handcart, an arrester, a cable and a grounding switch are arranged in the cable room, and a current transformer is arranged on the back wall of the cable room. The high-voltage switch cabinet disclosed by the invention has the advantages that the bus sleeve covers the bus so that the insulation distance between buses and the insulation distance between each bus and the cabinet shell are reduced, and the size of the high-voltage switch cabinet is shortened; a cable room cabinet door is changed from a traditional clapboard type into a rotary shaft type, so that the cable room cabinet door can be conveniently opened and the cable room can be conveniently overhauled; and in addition, the safety performance of the high-voltage switch cabinet is increased through components, such as a voltage leaking device and the arrester.

Description

High-tension switch cabinet
Technical field
The invention belongs to high pressure assembled electric equipment field, relate in particular to a kind of high-tension switch cabinet.
 
Background technology
High-tension switch cabinet is a kind of switchgear assembly and control appliance, and it is main with control, supervision, measurement and the protection done power circuit, main power consumption equipment as power center (PC) and main switching compound, standing transformer station, the switchgear house of placing.Electric elements comprise electric elements (major loop equipment) and secondary component (claim secondary device or auxiliary equipment again, be meant the low-voltage equipment that primary equipment is supervised, controls, measures, adjusted and protects) in the cabinet.
Need there be certain distance could not disturb and guarantee electrical safety mutually between the bus of high-tension switch cabinet; Refer to that mainly insulation distance and bus are to the insulation distance of cabinet between bus; Often make that the bus-bar room volume of high-tension switch cabinet is bigger, be unfavorable for the miniaturization of electric equipment.In addition, the baffle-type door is adopted at the high-tension switch cabinet back side, and is fastening with a lot of screws; The observation window position that has is too high, and the observation window window that has is too little, equipment is maked an inspection tour observed inconvenience; Do not see the run location of ground connection disconnecting link, what the bottom, cable vault was equipped with lightning arrester does not see the lightning arrester operation conditions yet, establish earth connection when the cable line maintenance needs to identify no Denso; The cabinet door of opening the cable vault is difficult relatively, also need use special allen wrench.
 
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, the high-tension switch cabinet that a kind of size is relatively littler, the cabinet Men Yi of cable vault opens, security performance is good is provided.
To achieve these goals; The technical scheme that the present invention adopted is: high-tension switch cabinet; It is characterized in that: comprise cabinet shell, bus-bar room, circuit breaker cart chamber, cable vault, relay control room, described bus-bar room is provided with the bus by the bus casing parcel, and the circuit breaker cart chamber is provided with circuit breaker cart; Lightning arrester, cable and earthed switch place in the cable vault, and current transformer is positioned on cable vault's rear wall.
Aforesaid high-tension switch cabinet, the cable vault's cabinet door that is positioned at the back side, described cable vault is the rotary shaft door.
Aforesaid high-tension switch cabinet is provided with pressure relief device above described circuit breaker cart chamber, bus-bar room and cable vault.
Aforesaid high-tension switch cabinet, the below of described circuit breaker cart chamber is provided with withdrawable horizontal baffle and earthed switch operating mechanism.
Aforesaid high-tension switch cabinet is provided with dividing plate between described bus-bar room and the circuit breaker cart chamber.
Beneficial effect of the present invention: adopt bus casing parcel bus, dwindled between bus insulation distance and bus to the insulation distance of cabinet shell, the size of having dwindled high-tension switch cabinet; Change cable vault's cabinet door into rotary shaft by traditional iris type, make things convenient for cable vault's cabinet door unlatching, make things convenient for the maintenance of cable vault; Adopt parts such as pressure relief device and lightning arrester, strengthened the security performance of high-tension switch cabinet.
 
Description of drawings
Fig. 1 is a structural representation of the present invention;
State diagram when Fig. 2 opens for cable vault's cabinet door;
Wherein, 1 bus-bar room, short-circuiting device handcart chambers 2,3 cable vaults, 4 relay control rooms; 5 current transformers, 6 lightning arresters, 7 cables, 8 earthed switches, 9 buses; 10 circuit breaker carts, 11 dividing plates, 12 withdrawable horizontal baffles, 13 earthed switch operating mechanisms; 14 pressure relief devices, 15 bus casings, 16 cable vault's cabinet doors, 17 cabinet shells.
 
Embodiment
Fig. 1 is the preferred embodiments of the present invention, below in conjunction with accompanying drawing the present invention is further described.
According to Fig. 1; High-tension switch cabinet; It is characterized in that: comprise cabinet shell 17, bus-bar room 1, circuit breaker cart chamber 2, cable vault 3, relay control room 4, described bus-bar room 1 is provided with the bus 9 by bus casing 15 parcels, and circuit breaker cart chamber 2 is provided with circuit breaker cart 10; Lightning arrester 6, cable 7 and earthed switch 8 place in the cable vault 3, and current transformer 5 is positioned on cable vault's 3 rear walls; Cable vault's cabinet door 16 at 3 back sides, cable vault is the rotary shaft door; The top of circuit breaker cart chamber 2, bus-bar room 1 and cable vault 3 is provided with pressure relief device 14; The below of circuit breaker cart chamber 2 is provided with withdrawable horizontal baffle 12 and earthed switch operating mechanism 13; Be provided with dividing plate 11 between bus-bar room 1 and the circuit breaker cart chamber 2.
High-strength rail has been installed in circuit breaker cart chamber 2, supplies circuit breaker cart 10 in cabinet, to be moved by isolated location/test position and slides to the service position.Bus 9 is with the bus casing 15 of thermal shrinkage type, and lap-joint adopts fire-retardant T type insulating cover, has guaranteed reliable compound inslation.Switch cubicle adopts the middle structural design, and current transformer 5 is contained on cable vault's 3 rear walls, and earthed switch 8 is contained on the stationary barrier (not shown) of cabinet shell 17 inwalls, can avoid owing to the long torsional deformation that causes of earthed switch 8 operating axis; The space is big in the cable vault 3, can connect many cables 7, and cable 7 connects highly high, and cable end is easy for installation.The secondary device of relaying protection element, instrument, electrification display and specific (special) requirements can be installed by relay control room 4.Various handcarts all adopt screw mandrel to shake propelling, withdraw from switch cubicle, flexible and convenient operation.Above circuit breaker cart chamber 2, bus-bar room 1 and cable vault 3, be equipped with pressure relief device 14; When circuit breaker or bus 9 generation internal faults; Follow the appearance of electric arc, the switch cubicle internal pressure sharply raises, and the pressure of top installing discharges metallic plate (being pressure relief device 14) and will be opened automatically; Drain gas with release pressure, to guarantee the safety of operating personnel and switch cubicle.
The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop on protection scope of the present invention.
