Abstract
The utility model relates to a novel low-voltage isolating switch. The novel low-voltage isolating switch is characterized in that an insulation portion comprises an insulation support pillar and upper and lower covers of the insulation support pillar; the upper and lower covers of the insulation support pillar are equipped at both ends of the insulation support pillar; the insulation support pillar is equipped on a base plate through a bolt, a line-press bolt fastens a front contact which is fastened on the insulation support pillar through a bolt, a line-press bolt fastens a rear contact, a positioning axle base and the rear contact are fixed on the insulation pillar through bolts, and a shaft penetrates the positioning axle base. According to the novel low-voltage isolating switch, a novel disconnecting link structure coordinates with the positioning axle base, and the disconnecting links can be removed, so maintainers can carry out repair work such as safety piece replacement at a place away from a dangerous place, and the repair work is safer; and a device which is composed of a spring buckle bowl and a spring enables two rows of disconnecting links to keep a good distance and good clamping capability so as to make the disconnecting links not fall.
Description
Technical field
The utility model relates to a kind of isolating switch, particularly a kind of novel low pressure isolating switch.
Background technology
Isolating switch promptly when minute position, has the insulation distance of requirement up to specification and significantly breaks off sign between contact; When closing the position, can carry electric current and the exceptional condition switchgear of the electric current under the short circuit for example at the appointed time under the normal loop condition.But now existing like product has certain defective on the market: isolating switch can cause electric arc drawing, close in the process, but because the bearing capacity of monolithic disconnecting link is not enough, the contact of burning easily.In needs maintenance, safeguard, draw, when closing disconnecting link, need outside total lock to have a power failure, can impact other regional power supplies, cause greatly inconvenience, otherwise need be drop-down in charged situation, close a floodgate, can cause maintainer's personal safety greatly to threaten.
Summary of the invention
According to problem set forth above; The utility model is in order to overcome the problem of at present existing monolithic disconnecting link; By base plate (1), insulation column (2), insulation column covers (3), line ball bolt (4), front contact (5), snak link bowl (6), preceding cutter chi (7), lock hook (8), extension spring (9), operation ring fixed head (10), safety plate hold-down bolt (11), insulation board (12), pluck cutter ring (13), back cutter chi hook (14), location axle bed (15), axle (16), back contact (17), spring (18), location bushing pipe (19) and form; It is characterized in that insulating element comprises insulation column, insulation column covers; The insulation column covers is installed in the two ends of insulation column, and insulation column utilizes bolt to be installed on the base plate, and the line ball bolted is in front contact; Front contact with bolted on insulation column; The line ball bolted is contact in the back, with bolt will locate axle bed, afterwards contact is fastened on the insulation column, and axle is passed the location axle bed.
Said back cutter chi hook, insulation board, preceding cutter chi connect with the safety plate hold-down bolt successively, and double disconnecting link utilizes bolt to connect; The centre utilizes positioning adapter spacing, and both ends of the spring mounting spring button bowl is installed in the bolt two ends with this device; Pluck the cutter ring and be installed on the side tool lock, safety plate utilizes the safety plate hold-down bolt to connect, cutter chi hook after the disconnecting link utilization; Be mounted on the axle of location axle bed, locking member comprises operation ring fixed head, lock hook, extension spring, and operation ring fixed head utilizes bolt to be installed in the middle of two disconnecting links; Lock hook is installed on the operation ring fixed head, and utilizes extension spring attended operation ring fixed head and lock hook, and locking member can be sealed with front contact.
The utility model beneficial effect is: through changing the monolithic disconnecting link into the biplate disconnecting link, simultaneously two safety plates can be installed, strengthen the bearing capacity of disconnecting link; Avoid the contact burn, the life-span that has increased product changes the disconnecting link that is connected into carried hanging type, and the maintainer can be under the situation of not cutting off the power supply; Utilize insulating bar that disconnecting link is drawn back, take, after the maintenance; Utilize insulating bar that disconnecting link is hung up again, closure has made things convenient for maintainer's maintenance process.New disconnecting link structure matches with the location axle bed, can disconnecting link be taken, and makes the maintainer change service works such as safety plate in the place away from the deathtrap, and is safer; The device that snak link bowl and spring are formed can make two row's disconnecting links keep distance and chuck(ing) capacity preferably, makes the disconnecting link difficult drop-off.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the detail structure chart of the utility model.
Embodiment
Like Fig. 1, shown in Figure 2 should installing by novel low pressure isolating switch, live wire and zero line are pressed on the forward and backward contact with corresponding line ball bolt respectively.After the current overload of circuit blew safety plate, the maintainer can utilize insulating bar to draw back lock hook under the condition that total lock does not cut out with the outside, disconnecting link is drawn back, and choose and pluck the cutter ring, disconnecting link is plucked from the location axle bed of isolating switch left.After having changed safety plate, profit uses the same method, and disconnecting link is hung got back on the axle bed of location, and closed disconnecting link.Because this novel disconnecting link is two-row structure, improved bearing capacity, draw, when closing disconnecting link, the electric arc of generation is difficult for making contact to burn.
