Abstract
A magnetic switch structure for an explosion-proof motor is provided. An inductive control panel in connection with a power switch is arranged at the inner side of a rear cover of the explosion-proof motor. A switch body is arranged at outer side of the rear cover. Inductive magnetic steel is arranged at a position of the front end of the switch body corresponding to the inductive control panel. The magnetic switch structure prevents interference of external magnets through a control panel magnetic conductive ring, a switch magnetic conductive ring and a switch cover plate, so that unstable factors of common magnetic switches are minimized. Non-contact switch style can achieve explosion-proof and protection effects more easily, and thus the performance of the explosion-proof motor is substantially improved.
Description
Technical field
The present invention relates to a kind of flame-proof electric motor magnetic switch structure of protective, can be used as the magnetic switch parts of flame-proof electric motor, also can be used as independent explosion-proof magnetic switch.
Background technology
Flame-proof electric motor switch, is one of flame-proof electric motor key structure, and its structure quality directly affects flame-proof electric motor performance.At present, flame-proof electric motor switch is generally mechanical switch, and switch body is directly connected with flame-proof electric motor inner chamber switch, and it is explosion-proof, safeguard procedures relative complex, thereby has the quality factors of instability to exist.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of dependable performance, simple in structure, easy to maintenance is provided, be suitable for the flame-proof electric motor magnetic switch structure that the special occasions such as explosion-proof, dustproof, waterproof use.
Technical scheme of the present invention is: flame-proof electric motor bonnet inner side is provided with the induction control board being connected with mains switch; Switch body is loaded on bonnet outside; Switch body front end and induction control board correspondence position are provided with and the inductive magnetic steel of responding to control board and coordinate to control mains switch.
Described induction control board is arranged with the control board magnetic guiding loop that prevents external magnetic interference outward; Described inductive magnetic steel is arranged with the switch magnetic guiding loop that prevents external magnetic interference outward.
Described switch body is loaded on bonnet outside through switch cover plate; Switch cover plate is permeability magnetic material; Described permeability magnetic material is the material that relative permeability is higher.
Described induction control board is connected by cable with mains switch.
Described mains switch comprises relay.
Described induction control board is made up of Hall element, drive circuit.
Described induction control board is made up of magnetic reed switch, drive circuit.
Described induction control board and inductive magnetic steel are placed in respectively outside in flame-proof electric motor bonnet; Induction control board and inductive magnetic steel are positioned on same axis.
The present invention, owing to adopting above technical solution, makes Hall element or the magnetic reed switch action in flame-proof electric motor thereby realize magnet steel rotation generation magnetic force, carrys out driving power switch, completes mains switch action.The maximum feature of the present invention is by control board magnetic guiding loop, switch magnetic guiding loop and switch cover plate, prevents the interference of external magnetic, thereby reduces general magnetic switch destabilizing factor; Adopt non-contacting on-off mode more easily to realize explosion-proof and protective action, thereby flame-proof electric motor performance is improved greatly, there is significant social benefit.

Fig. 2 is the enlarged drawing of part of the present invention in Fig. 1.
Fig. 3 is that the present invention is separately as the application schematic diagram of magnetic switch.
In figure, 1, mains switch, 2, induction control board, 3, control board magnet ring, 4, bonnet, 5, inductive magnetic steel, 6, switch cover plate, 7, switch body, 8, switch magnetic guiding loop.
Embodiment
In Fig. 1, Fig. 2, the present invention is made up of mains switch 1, induction control board 2, control board magnetic guiding loop 3, bonnet 4, inductive magnetic steel 5, switch cover plate 6, switch body 7, switch magnetic guiding loop 8.Floatless switch magnetic guiding loop 8 on the endoporus circumference corresponding with inductive magnetic steel 5 of bonnet 4 flame-proof electric motors outsides, fixes control board magnetic guiding loop 3 on the bonnet flame-proof electric motor inner chamber endoporus circumference corresponding with responding to control board 2; The endoporus corresponding with inductive magnetic steel 5 and endoporus respectively bonnet flame-proof electric motor in the outside corresponding with induction control board 2 on bonnet 4; After switch body 7 is fixing through switch cover plate 6 and inductive magnetic steel 5, can rotate along switch body 7 axis, and fix by switch cover plate 6 and bonnet 4 outsides; Switch cover plate 6 is the material that relative permeability is higher; Induction control board 2 is made up of hall sensing element or magnetic reed switch and drive circuit, and is fixed in the endoporus of bonnet 4 flame-proof electric motors inner sides; Mains switch 1 is made up of relay etc.Induction control board 2 is connected by cable with mains switch 1.
The course of work and principle: rotary switch body 7, inductive magnetic steel 5 rotates, the Hall element on the magnetic force induction control board 2 of generation or magnetic reed switch action, thereby the folding of driving next stage relay, control power supply.The effect of control board magnetic guiding loop 3, switch magnetic guiding loop 8 and switch cover plate 6 is to prevent the interference of external magnetic to hall sensing element or magnetic reed switch, prevents switch misoperation, opens folding also thereby be delivered to reliably as required next stage power supply.
Because induction control element is at inner chamber, switch body is in flame-proof electric motor outside, two chambeies separate, do not communicate, thereby pass through the switch body in the outside of the bonnet of operation flame-proof electric motor, the mains switch that can control cover cavity after flame-proof electric motor, makes flame-proof electric motor have good explosion-proof, protective.
In Fig. 3,1 is mains switch, and 2 is induction control board, and 3 is control board magnet ring, and 4 is bonnet, and 5 is inductive magnetic steel, and 6 is switch cover plate, and 7 is switch body, and 8 is switch magnetic guiding loop.
