Abstract
The utility model discloses a lower voltage fuse isolation switch comprising a buckle sleeve pipe and an isolation switch body arranged in the buckle sleeve pipe; an insulation plate is fixed between an upper movable contact and a lower movable contact of the isolation switch body through bolts; two side portions of the upper movable contact and the lower movable contact are respectively connected with connecting plates; fuses are arranged between the connecting plates on one side portion. The isolation switch body is arranged in the buckle sleeve pipe prepared by an insulation material; the buckle sleeve pipe can shield and protect the isolation switch, and can prevent switch short service life caused by exposure to the sun and rain; the mounting positions of conventional fuses are changed to the side portion from the top portion of the upper movable contact and the lower movable contact, so the current path is changed, and certain distance is kept between the fuses and the insulation plate; the bolts can only fix and connect the insulation plate, so the insulation plate cannot be heated and burned by overlarge load; the lower voltage fuse isolation switch reduces replacing rate of the equipment and maintenance cost, ensures power supply time, and improves power supply reliability.
Description
Technical field
The utility model belongs to power switch technical field, particularly a kind of low voltage fuse type isolating switch.
Background technology
As everyone knows, at present, low voltage fuse type isolating switch is widely used for the outlet of bench type step down side owing to having advantage cheap, stable, easy to maintenance.But when peak of power consumption, load are multiplied, the easily heating of fuse contact bolt crimping point, insulation board blows phenomenon because heating causes and happens occasionally, not only need to change, and cause power failure because of insulation board heating burnout, the economic benefit that has directly affected power supply enterprise, also causes inconvenience to the user.
Utility model content
The utility model is to solve above-mentioned technical barrier, and a kind of low voltage fuse type isolating switch of simple in structure, easy to use, dependable performance is provided.
For achieving the above object, the technical solution adopted in the utility model is: a kind of low voltage fuse type isolating switch, comprise and fasten the isolating switch body of installing in sleeve pipe and described fastening sleeve pipe, between the upper moving contact of described isolating switch body and lower moving contact, be bolted insulation board, the both sides of described upper moving contact and lower moving contact are connected with respectively connecting plate, between the described connecting plate of a side, fuse are set.
Described fastening sleeve pipe is insulating material product, and described fastening sleeve pipe two ends arrange line opening.
Described connecting plate is curved panel structure, fuse described in setting at least two groups on described connecting plate.
On described insulation board, central dividing plate is set, described central dividing plate is ceramic objects.
The utility model provides a kind of low voltage fuse type isolating switch, its reasonable in design is novel, described isolating switch body is arranged in the fastening sleeve pipe of insulating material making, utilize described fastening sleeve pipe to block protection to isolating switch, avoid exposing to the sun and rain and cause the lost of life, the installation site of traditional insurance silk is changed into sidepiece by the top of upper moving contact and lower moving contact, changed current path, making has certain distance between fuse and insulation board, described bolt only works to be connected and fixed insulation board, can not blow insulation board because of excessive heating of loading, reduced the turnover rate of equipment, reduced maintenance cost, guaranteed power-on time, improved power supply reliability, described connecting plate is curved panel structure, more be adapted to described sleeve-shaped, guarantee that described fuse and insulation board spacing have suitable distance, fuse described in setting at least two groups on described connecting plate, can tackle high-power high loaded process state, on described insulation board, central dividing plate is set, further each section of fuse splits, avoid influencing each other of sub-thread scaling loss.The utility model is simple in structure, connects reliably, has increased the economic benefit of power supply enterprise, has good value for applications.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is a kind of structural representation of the utility model.
Embodiment
As shown in Figure 1, a kind of low voltage fuse type isolating switch, comprise the isolating switch body that fastens sleeve pipe 1 and described fastening sleeve pipe 1 interior installation, between the upper moving contact 2 of described isolating switch body and lower moving contact 3, by bolt 4, be fixed with insulation board 5, the both sides of described upper moving contact 2 and lower moving contact 3 are connected with respectively between the described connecting plate 6 of connecting plate 6, one sides fuse 7 are set.
Described fastening sleeve pipe 1 is insulating material product, and described fastening sleeve pipe 1 two ends arrange line opening.
Described connecting plate 6 is curved panel structure, fuse 7 described in setting at least two groups on described connecting plate 6.
On described insulation board 5, central dividing plate is set, described central dividing plate is ceramic objects.
The utility model provides a kind of low voltage fuse type isolating switch, its reasonable in design is novel, described isolating switch body is arranged in the fastening sleeve pipe of insulating material making, utilize described fastening sleeve pipe to block protection to isolating switch, avoid exposing to the sun and rain and cause the lost of life, the installation site of traditional insurance silk is changed into sidepiece by the top of upper moving contact and lower moving contact, changed current path, making has certain distance between fuse and insulation board, described bolt only works to be connected and fixed insulation board, can not blow insulation board because of excessive heating of loading, reduced the turnover rate of equipment, reduced maintenance cost, guaranteed power-on time, improved power supply reliability, described connecting plate is curved panel structure, more be adapted to described sleeve-shaped, guarantee that described fuse and insulation board spacing have suitable distance, fuse described in setting at least two groups on described connecting plate, can tackle high-power high loaded process state, on described insulation board, central dividing plate is set, further each section of fuse splits, avoid influencing each other of sub-thread scaling loss.The utility model is simple in structure, connects reliably, has increased the economic benefit of power supply enterprise, has good value for applications.
