Abstract
The utility model discloses an oncontacting point type power switch, including switch shell, permanent magnet and switch box, the switch box is upper end open -ended cuboid structure, its install in switch shell's bottom, one side of switch shell is provided with the switch lever, the switch lever pass through the rotation axis install in switch shell is last, the switch lever is located one end in the switch shell is provided with the bearing, install the pull rod on the bearing, the below of pull rod is connected with the permanent magnet. The utility model discloses an utilize the magnetism of permanent magnet, it is rotatory from top to bottom to adsorb the switch piece, and when the switch piece was kept away from to the permanent magnet, the switch piece fell, circuit conduction, and when the permanent magnet was close to the switch piece, the switch piece rose, the circuit beginning for disappearance electric arc open fire flower when switching on and turn -offing, the action is rapidly, and is longe -lived, and the reliability is high, is fit for fire prevention, special environment use such as explosion -proof, dampproofing.
Description
Technical field
The utility model relates to a kind of power switch, particularly relates to a kind of non-contact type power switch.
Background technology
At present, high-voltage switch gear is primarily of three kinds of forms such as oil-minimum breaker, vacuum circuit-breaker, SF6 circuit breakers, and they can produce electric arc in switching circuitry processes, and pressure arc extinguishing process can produce current break in various degree, causes overvoltage and electromagnetic interference phenomenon; Switching perception or capacitive load as transformer, motor, Capacitor banks time, very large transient current can be produced, thus the normal use of electrical network and electric equipment stability and electric equipment is had an impact.
Utility model content
The purpose of this utility model is just to provide a kind of non-contact type power switch to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises switch case, permanent magnet and switch enclosure, described switch enclosure is the rectangular structure of upper end open, it is installed on the bottom of described switch case, the side of described switch case is provided with switch lever, described switch lever is installed in described switch case by rotating shaft, one end that described switch lever is positioned at described switch case is provided with bearing, and described bearing is provided with pull bar, and the below of described pull bar is connected with described permanent magnet.
The utility model is preferred, and be provided with two conducting strips in left and right in described switch enclosure, wherein a described conducting strip is connected with switch plate near one end of conducting strip described in another root described by rotary screw.
The utility model is preferred, and the side that described switch case is positioned at described switch lever is provided with arc card, and described arc card is provided with the fastener that can engage described switch lever.
The beneficial effects of the utility model are:
The utility model is by utilizing the magnetic of permanent magnet, and absorption switch plate rotates, up and down when permanent magnet is away from switch plate, switch plate falls, circuit turn-on, when permanent magnet is near switch plate, switch plate rises, the circuit beginning, make not occur electric arc open fire flower during turn-on and turn-off, be swift in motion, the life-span is long, reliability is high, is applicable to particular surroundings uses such as preventing fires, explosion-proof, moistureproof.
Accompanying drawing explanation
