Technical field
The present invention relates to electric power checkout equipment field, especially a kind of 10 kilovolts of enclosed switch opening devices that handcart-type high voltage mid-placed cabinet nuclear phase is used.
Background technology
In recent years, along with socioeconomic development, no matter be enterprise or resident, all power supply reliability is had higher requirement, for meeting client's this demand, actively carry out the ring network power supply mode between circuit and circuit.In the time that certain part of circuit breaks down, isolated fault position at short notice, from both sides switch to non-faulty section client normal power supply, can avoid like this electrical network occurrence of large-area power outage, shorten the breakdown repair time, can also reduce loss of outage, ensure to greatest extent the reliable electricity consumption of client.And will complete before ring network power supply mode, most important is exactly to need the interior bus of switch cubicle and line side to keep the consistency of phase place, otherwise will cause short trouble, the reliability of serious threat power supply.
At present, the multiplex handcart-type high voltage mid-placed cabinet of line segregation in distribution switching station, carry out bus and line side nuclear phase in cabinet time, generally there are four people to carry out, one people's monitoring, the enclosed switch that two personal link rods withstand respectively switch cubicle both sides simultaneously just can be opened switch cubicle sealing isolation plate washer, and maintains, then two people stretch into switch cubicle fixed contact wireless nuclear phase stick again and carry out nuclear phase.In such operating process, link rod exists the risky operation personnel of slippage in the time firmly opening sealing isolation plate washer with link rod, once side's slippage, people likely enters in cabinet, at that time, one of plate washer of sealing isolation is opened, a sealing, the distance of operating personnel and charging equipment will be less than safe distance, causes personal injury; And must two people exert oneself simultaneously, can open, if firmly uneven, can make sealing isolation baffle plate seal suddenly, block wireless nuclear phase stick, cause nuclear phase stick fracture, if nuclear phase probe breaks in fixed contact, will expand power failure range, affect power supply reliability.
Summary of the invention
The object of the invention is the deficiency in order to solve above-mentioned technology and a kind of 10 kilovolts of handcart-type high voltage mid-placed cabinet enclosed switch opening devices are provided, substitute the artificial link rod opening enclosed switch of using, avoid manually-operated danger, safe; The enclosed switch stress equalization of switch cubicle both sides, reliability is strong.
In order to achieve the above object, 10 kilovolts of handcart-type high voltage mid-placed cabinet enclosed switch opening devices that the present invention is designed, it comprises a horizontal fixed mount, described fixed mount two ends be respectively equipped with one with fixed mount right angle arrange guide rail, the centre of described fixed mount has circular hole, one screw rod is located in the internal diameter that described circular hole diameter interior and screw rod end is greater than described circular hole, the leading portion of the described screw rod movable stand that is parallel to fixed mount that is spirally connected, the baffle plate with through hole is equipped with in the top of described movable stand, the two ends of described movable stand be respectively equipped with one with movable stand right angle arrange pressing plate, the lower end of described pressing plate is provided with can be at the wheel of corresponding guide rail top offset, the front end of described pressing plate is vertical splenium, described screw rod, guide rail and pressing plate are arranged in parallel and are all positioned at a side of fixed mount.
Technique scheme in use, first fixed mount is fixed on high voltage mid-placed cabinet switch cubicle, rotating screw bolt, make movable stand along guide rail to switch cubicle inner side, until the enclosed switch of switch cubicle both sides is opened respectively and withstood to two pressing plates, the sealing isolation baffle plate of switch cubicle is opened, now staff can carry out nuclear phase operation, this technical scheme has substituted the artificial link rod opening enclosed switch of using, and avoids manually-operated danger, safe; The enclosed switch stress equalization of switch cubicle both sides, reliability is strong.
As optimization:
Described fixed mount comprises a fixed head and is movably connected in respectively two portable plates at fixed head two ends, described guide rail is fixed on a corresponding portable plate, because switch cubicle size is entirely not identical, therefore portable plate is set, the length that can adjust according to actual needs fixed mount, the scope of application is wider.
Described movable stand comprises a transverse slat and is movably connected in respectively two expansion plates at transverse slat two ends, and described pressing plate is fixed on a corresponding expansion plate, matches with portable plate, with entering with moving back, adjusts in real time.
Described baffle plate is symmetrical arranged and is formed by two poly (methyl methacrylate) plates, described poly (methyl methacrylate) plate is provided with the handle hole of upper and lower two side openings, two poly (methyl methacrylate) plates can have lap, and formation elasticity adjustment distance, is fixed frame and movable stand elongates or shortens operation.
Described poly (methyl methacrylate) plate is bolted on expansion plate, and for convenience detach and installation, is convenient to dismantle rear transport.
Described fixed head lateral surface is provided with two symmetrically arranged handles, conveniently lifts.
10 kilovolts of handcart-type high voltage mid-placed cabinet enclosed switch opening devices of one that the present invention obtains, while being applicable to nuclear phase, mechanical type is opened high pressure enclosed switch and maintains, and avoids manually-operated danger, safe; And the enclosed switch stress equalization of switch cubicle both sides, reliability is strong.
