An electromagnet is arranged in a shell, one end of a coil on the electromagnet is grounded, and the other end is connected with an outer shell of a power utilizing device; an insulating rod is arranged above the electromagnet, and the position of the insulating rod, which corresponds to the electromagnet, is coated with a thick armature layer; the position of the insulating rod, which corresponds to the leading-in wiring terminal of a three-phase (or single-phase) power supply of the shell, is provided with corresponding contact points; the contact points are correspondingly connected with the leading-out wiring terminal of the three-phase (or single-phase) power supply of the outer shell.
Description
The utility model relates to a kind of earth leakage protective device.
In case available dynamic power supply and the electric leakage of civilian mains supply power consumption equipment, danger is very big, can cause casualties and the initiation fire accident.For addressing this problem, existing at present earth leakage protective device comes into the market.But this short earth leakage protective device must be to touch under the situation that electrical appliance electric leakage shell causes power supply short circuit the user just to cut off the electricity supply.Still there is certain danger in this mode, can not guarantee 100% safety, and easily burns earth leakage protective device during power supply short circuit.Existing in addition earth leakage protective device only is applicable to the electrical appliance of single-phase mains supply, and can not be used for the power consumption equipment of electrical source of power, and application surface is narrow.
The purpose of this utility model is exactly in order to address the above problem, provide a kind of fail safe reach 100% and the long service life electric leakage of using face width cut non-electricity protector.
Technical solution of the present utility model:
Non-electricity protector is cut in a kind of electric leakage; it includes housing (1); be connected to three-phase (or single-phase) electric power incoming line binding post (2) and outlet binding post (3) on the housing (1); outlet column (3) is drawn three-phase (or single-phase) power supply and is connected with power consumption equipment (4); it is characterized in that in housing (1), being provided with electromagnet (5); coil (6) one end ground connection above it; the other end is connected with power consumption equipment (4) shell; electromagnet (5) top is provided with insulating bar (7); the position of the corresponding electromagnet of this insulating bar (7) (5) is enclosed with thick armature layer (8); the position of insulating bar (7) corresponding housing (1) three-phase (or single-phase) electric power incoming line binding post (2) is provided with corresponding contact point (9), and the lead-in wire of these contact points (9) by separately and the corresponding connection of three-phase (or single-phase) power outlet binding post (3) of housing (1).
The utility model utilizes the electric leakage of power consumption equipment to pass to work of electromagnet, and it is cut off the electricity supply, and its security reliability improves greatly, reach 100%, as long as power consumption equipment has leaky to take place at work, the utility model just cuts off operating circuit immediately, avoids the generation of accident.The utility model is rational in infrastructure, and cost is low, high safety, and need not to protect by short circuit, so improve useful life greatly.The utility model is not only applicable to the electrical appliance of single phase poaer supply, is equally applicable to the power consumption equipment of three phase mains, uses face width.
Fig. 1 is a structural representation of the present utility model.
As Fig. 1, the opposite side position of the utility model corresponding its electric power incoming line binding post (2) in housing (1) is provided with column (10), insulating bar (7) is hinged with it, and be connected with balancing spring (11) between same side that insulating bar (7) is hinged and housing (1) the inner bottom surface relevant position, corresponding insulating bar (7) is provided with spring discount (12) near an end of electric power incoming line binding post (2) position in the housing (1), an its middle part corresponding end common and insulating bar (7) closely pastes and touches, each contact point (9) on the assurance insulating bar (7) and the corresponding connection of electric power incoming line binding post (2) of housing (1), and when electromagnet (5) adhesive, the lower end of spring discount (12) is pressed on the top of the same end of insulating bar (7), and the contact point (9) on the insulating bar (7) is thrown off with the electric power incoming line binding post (2) of housing (1).
Operation principle of the present utility model such as Fig. 1 are to be example with the three phase mains among the figure.Generally, be under the uncharged situation of power consumption equipment (4) shell, coil does not have electric current to pass through on (6), electromagnet (5) is not worked, insulating bar this moment (7) is closely pasted by the spring discount (12) in the housing (1) and touches, be in poised state, three contact points (9) on it and the corresponding connection of three phase mains inlet wire binding post (2), and make its operate as normal to power consumption equipment (4) power supply by three three phase mains outlet binding posts (3).In case take place to leak electricity when making power consumption equipment (4) outer casing electrification, then the coil (6) on the electromagnet (5) in the housing (1) has electric current to pass through, make electromagnet (5) produce the thick armature layer (8) of magnetic force adhesive insulating bar (7), making an end of the band contact point (9) of insulating bar (7) throw off spring discount (12) rotates around the pin joint of itself and column (10), be pressed on the top of the same end of insulating bar (7) until the lower end of spring discount (12), three contact points (9) of insulating bar this moment (7) are thrown off with three phase mains inlet wire binding post (2), reached the purpose of cutting off the electricity supply automatically, security reliability reaches 100%.After fault is got rid of, outside housing (1), pull spring discount (12), then insulating bar (7) makes an end of its band contact point (9) be upturned under the restoring force effect of balancing spring (11), heavy closely the subsides by the middle part of spring discount (12) touched, contact point (9) on the insulating bar (7) is communicated with electric power incoming line binding post (2) again, power supply to power consumption equipment (4) power supply, guarantees its trouble free service heavily again.
