Description
The utility model relates to the switching device that power supply or distribution are used, especially a kind of high voltage vacuum switchgear cabinet that adopts the drawer type vacuum circuit-breaker and mechanical locking device is arranged.
The 6-10KV high-tension switch cabinet that the existing power distribution of China is used, its circuit breaker mostly adopt fixed and the pusher two kinds of structures of handcart.Especially the sort of use is the fixed high-pressure vacuum switch cabinet more widely, and is simple in structure and cheap.But because the circuit breaker that this high voltage vacuum switchgear cabinet uses is fixedly mounted on cabinet inside, overhaul in case break down, interruption duration is just long.The staff gos deep into cabinet internal overhaul electric elements simultaneously, and danger is also bigger.The high voltage vacuum switchgear cabinet of handcart push type though it is more convenient to change circuit breaker, because the volume ratio of handcart part is bigger, promotes heavyly, and complex structure in addition is so the interchangeability of this high voltage vacuum switchgear cabinet is poor.Though the unit that has has at present used the propulsion plant of drawer type, the drawer shortage mechanical locking device correspondingly of circuit breaker often is housed, so safety is inadequately overhauled in operation.
The purpose of this utility model is little, simple in structure and have a drawer type high voltage vacuum switchgear cabinet of multi-functional mechanical locking device with regard to being to provide at the deficiencies in the prior art a kind of volume.
The purpose of this utility model is achieved in that
This high voltage vacuum switchgear cabinet by cabinet, preceding to the doorstep, preceding Xiamen and control room, bus-bar room, cable vault, drawer chamber and insulating barrier form, be provided with the secondary valve in the control room, be provided with bus geometrical clamp, porcelain vase and static socket in the bus-bar room, be provided with current transformer, earthed switch, piezo-resistance and zero sequence current mutual inductor in the cable vault, cable entry is located at the bottom of cable vault; Mainly be to be provided with guide rail and the drawer type spacer assembly of forming with drawout chassis, vacuum circuit-breaker and moving plug is set on guide rail in that drawer is indoor, be provided with by the interlocking major axis in the cabinet bottom and be fixed on the mechanical locking device that divide-shut brake pointer, blocking lever, stop collar, earthed switch connector, crank arm, locating shaft and shrouding lock pin on the interlocking major axis are formed, be provided with spring and push rod at interlocking major axis and shrouding lock pin socket place; Preceding electric current dial gauge, indicator light and the change over switch of being provided with to the doorstep of high voltage vacuum switchgear cabinet; The preceding Xiamen of high voltage vacuum switchgear cabinet be provided with observation window, once simulate board, closing by hand location hole, manual brake separating location hole, manually energy storage location hole, drawer are imported and exported location hole and emergency unlocking device.
The utility model advantage compared with prior art:
The one, combine the advantage of fixed high-voltage switch cubicle and handcart type high-voltage switch cabinet, the release unit that has light drawer and can exchange, the interruption duration when having significantly reduced maintenance.
The 2nd, because withdrawable circuit breaker is arranged on the guide rail, is furnished with bearing wheel on the drawout chassis, and has the transmission crank to advance by leading screw, so being housed, the drawer of circuit breaker passes in and out steadily, can prevent the fault that occurs because of dynamic and static contact loose contact effectively.
The 3rd, because of in cabinet, being provided with the multi-functional mechanical locking device,, improved the coefficient of safety of this high voltage vacuum switchgear cabinet greatly so can prevent the harm that brings because of misoperation effectively.
The 4th, owing to taked full-closed structure and high-strength insulating material, so barrier propterty is good, can prevent effectively that the electric elements corrosion is aging in the cabinet, to prolong the useful life of switch cubicle.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is the utility model Facad structure schematic diagram;
Fig. 2 is the utility model side structure schematic diagram;
Fig. 3 is the utility model mechanical locking device structural representation.
As shown in drawings, this mining drawer type high voltage vacuum switchgear cabinet is totally enclosed high voltage vacuum switchgear cabinet, by cabinet 1, preceding to the doorstep 3, preceding Xiamen 6 and control room 25, bus-bar room 16, cable vault 21 and drawer chamber 28 form, be equipped with insulating barrier 26 between each chamber, be provided with secondary valve 24 in the control room 25, being provided with 15, buses of bus geometrical clamp 14 and porcelain vase in the bus-bar room 16 is connected with static socket 17; Be provided with current transformer 18, earthed switch 20, piezo-resistance 19 and zero sequence current mutual inductor 22 in the cable vault 21, static socket 17 lower ends are connected with current transformer 18 and the lower end of current transformer 18 are connected piezo-resistance 19, piezo-resistance 19 is connected with earthed switch 20, and zero sequence current mutual inductor 22 and cable entry 23 all are located at the bottom of cable vault 21; In drawer chamber 28, be provided with guide rail 32, on guide rail 32, be provided with drawout chassis 31, the drawer type spacer assembly 30 that vacuum circuit-breaker 29 and moving plug 27 are formed, in cabinet 1, also be provided with by interlocking major axis 44 and be fixed on the divide-shut brake pointer 34 of interlocking on the major axis 44, blocking lever 36, stop collar 38, earthed switch connector 39, crank arm 43, the mechanical locking device 35 that locating shaft 42 is formed, front end at interlocking major axis 44 is provided with the transmission crank, its rear end is socketed with shrouding lock pin 45, with the interlocking major axis 44 of shrouding lock pin 45 socket places on be provided with spring 40 and push rod 41, slide and locking with control interlocking major axis 44 front and back; The preceding of cabinet 13 is provided with electric current dial gauge 2, indicator light 4 or button and change over switch 5 to the doorstep; On the preceding Xiamen 6 of cabinet 1, also be provided with observation window 7, once simulate board 8, closing by hand location hole 9, manual brake separating location hole 10, manually energy storage location hole 13 and emergency unlocking device 12.
