Abstract
The utility model relates to a wireless remote control falling fuse comprising a high-tension porcelain insulator, a fuse tube, a high-voltage connection terminal, an actuating device and a control structure. One end of the fuse tube is electric connected with the high-voltage connection terminal; the other end of the fuse tube is connected with the movable contact which is linked with high-voltage connection terminal by the corresponding stable contact, the peripheral stable contact provide a arc extinguishing chamber which is made of insulating rubber, openings are side provided in the transfer direction of the movable contact and the stable contact, oxide layer formation when the movable contact and the stable contact corresponding can be reduced, the tripping electric arc of the movable contact and the stable contact can be blocked. Destroying low-voltage electrical apparatus can be avoided, a protected switch has the advantages of flexibility remote operation, safety, fiduciary, and adapt for high-voltage power transformer.
Description
Technical field
The utility model relates to the high voltage drop-out type fuse cutout on a kind of electrical network, particularly about a kind of wireless remote control fuse switch.The utility model is applicable to the on high-tension side protection switch of power transformer.
Background technology
Between the high-tension line of electric power network and transformer, high voltage drop-out type fuse cutout is housed all, the needs of being convenient to transformer equipment and line upkeep maintenance or rationing the power supply.Common high voltage drop-out type fuse cutout, generally by high-tension porcelain insulator, fuse tube, high-voltage switch gear wiring, fuse tube one end and the wiring of porcelain vase high-voltage switch gear flexibly connect, the other end is connected on the porcelain vase by the movable shackle of fuse, when separating brake or combined floodgate, needs use special high-pressure insulating rod is manually pushed to or is left behind, operating personnel need dress insulation boots and insulating gloves during work, operate cumbersome, and security incident takes place easily, when rain waiting bad weather operation, be very easy to take place the personal safety accident especially.For this reason, the Chinese patent publication number is wireless remote control and the manual dual-purpose fuse switch of CN2456308, on the fuse Removable hook, driving mechanism is set, driving mechanism comprises motor part and mechanical part: mechanical part comprises frame, movable push bar, movable connecting shaft, movable push bar links to each other with movable connecting shaft, and the other end links to each other with armature on the frame; The motor section branch comprises motor, power supply and remote control control cabinet.Its remote control control cabinet receives the control of remote controller signal, control motor forward or reverse, the separating brake or the combined floodgate of realization fuse, easy to operate, safety.The separating brake or the combined floodgate of so-called fuse, promptly the location status by fixed contact that is connected with the high pressure inlet wire and the moving contact that is connected with fuse tube is determined, is gate-dividing state when both disconnect, and is "on" position during both closures.Therefore, the flexibility and reliability action is very important between maintenance fixed contact and the moving contact.Yet, existing various fuse switch, its fixed contact and moving contact position all are open-air structures, under long-term exposing to the sun and rain (most of the time is in closure state between the two), behind the fixed contact of making by copper material and moving contact oxidation, increase bonding force between the two, make the uncontrollable fuse separating brake of motor-driven moment, cause straighforward operation malfunctioning; In addition, for the electric arc that prevents to operate a switch damages low voltage equipment, existing fuse switch is provided with plastics arc extinguishing baffle plate in the fixed contact both sides, is very easy under the operational environment of this plastics arc extinguishing baffle plate under exposing to the sun and rain wear out and drops, and useful life is low.
Summary of the invention
One of the purpose of this utility model is the problem that exists at prior art, provides a kind of straighforward operation flexible, reliable wireless remote control fuse switch;
Two of the purpose of this utility model is the problems that exist at prior art, provide a kind of arc-extinguish chamber be difficult for aging, the life-span is long, can eliminate electric arc damage low voltage equipment when operating a switch, the wireless remote control fuse switch of handling safety.
The technical scheme that realizes the utility model purpose comprises high-tension porcelain insulator, fuse tube, high-voltage connection terminal, driving mechanism, control structure, fuse tube one end is electrically connected with following high-voltage connection terminal, the other end is connected with moving contact, this moving contact is by being connected with last high-voltage connection terminal with its fixed contact that cooperatively interacts, mainly be that the fixed contact periphery is provided with an arc-extinguish chamber, this arc-extinguish chamber is made by electro-insulating rubber, is shaped on opening at a fixed contact and a moving contact deciliter direction of action side.
In above technical scheme, be provided with interior arc-extinguish chamber between fixed contact and the arc-extinguish chamber, arc-extinguish chamber is made by electro-insulating rubber in this, is shaped on opening at a fixed contact and a moving contact deciliter direction of action side.
One of the utility model advantage compared with prior art is: fixed contact is installed in the arc-extinguish chamber, has isolated rainwater and sunlight, and the generation of oxide layer when reducing fixed contact and cooperating with moving contact makes between the two deciliter flexibly, straighforward operation flexibly, reliable;
Two of the utility model advantage compared with prior art is: fixed contact is installed in the arc-extinguish chamber, arc-extinguish chamber adopts the elastic silicone rubber material, be difficult for aging, the life-span is long, when the moving contact separating brake leaves arc-extinguish chamber, its opening closes up immediately, cut off fixed contact and moving contact separating brake electric arc, can not damage low voltage equipment, handling safety.
