Description
Technical field
The present invention relates to the earth leakage protective device field, particularly relate to a kind of permanent magnetism auxiliary starter earth leakage protective device.
Background technology
For the reason of electrical equipment Electrical Safety, earth leakage protective device is usually used in being connected between electrical equipment and the main power source.In general typical structure, earth leakage protective device is controlled a pair of or above contact between load and power supply at least, and comprises that minimum one is moved contact mechanical structure, joins the fixing contact of another side to.The effect of electromagnet is a pair of or above contact to be joined together and circuit turn-on.
Typical electromagnet generally the magnetic force that provides under the long applicable cases of stroke relatively a little less than, general design is at short notice electromagnet overload operation, to promote magnetic force usually.But the time of overload operation can not be kept much longer, otherwise situation overheated or that burn can appear in electromagnet.Yet earth leakage protective device will keep in touch in conducting state under the situation of running, is closed or leaks electricity up to it and trigger and cease to function.Therefore, the used electromagnet of this class earth leakage protective device must running continuously in long-time.
When starting in order to reduce institute must electric current and keep electromagnet attracting state the electric current of palpus; so that can allow electromagnet keep running at a lower temperature; with cost that reduces power consumption, saving electromagnet and the life-span that prolongs electromagnet, people wish that urgently a kind of permanent magnetism auxiliary starter earth leakage protective device comes out.
Summary of the invention
Technical problem to be solved by this invention is; design a kind of permanent magnetism auxiliary starter earth leakage protective device; this permanent magnetism auxiliary starter earth leakage protective device can reduce institute when starting must electric current and keep electromagnet attracting state the electric current of palpus; so that can allow electromagnet keep running at a lower temperature, reach the cost that reduces power consumption, saves electromagnet and prolong the electromagnet purpose in useful life.
The technical solution adopted for the present invention to solve the technical problems is: permanent magnetism auxiliary starter earth leakage protective device; comprise bearing; electromagnet; one permanent magnet; the swing sheet; the return assembly; fixing contact assembly; the electric-leakage detection circuit of mobile contact assembly and the action of control magnet switching; electromagnet and bearing are installed together; mobile contact assembly is assembled together with swing sheet one end; the swing sheet other end and return assembled are together; return assembly and bearing are assembled together, and the electric-leakage detection circuit of permanent magnet and the action of control magnet switching is assemblied in the bearing respectively.
In technique scheme, described electromagnet comprises plunger, secured core, coil rack and coil groups, coil groups and coil rack are assembled together, and plunger and secured core are assembled together with coil rack respectively, and permanent magnet and plunger outer end contact.
Described return assembly comprises a return spring, and return spring one end and bearing are inconsistent.
The invention has the beneficial effects as follows: 1, the permanent magnetism auxiliary starter earth leakage protective device of said structure, when leaky occurring, this protector can cut off electric current fast with fixedly contact assembly and mobile contact assembly disconnection, reaches the purpose of protection electrical appliance.Electromagnet is controlled by one group of electronic circuit; when electric circuit inspection takes place to leak current fault; circuit will stop to power to electromagnet; making fixedly, contact assembly separates automatically with mobile contact assembly; earth leakage protective device just stops the electrical appliance power supply to associated at once; avoid the danger of electric shock with the protection user, and protect electrical appliance, prevent to be burnt out.2, this permanent magnetism auxiliary starter earth leakage protective device can reduce institute when starting must electric current and keep electromagnet attracting state the electric current of palpus; so that can allow electromagnet keep running at a lower temperature, reach the cost that reduces power consumption, saves electromagnet and prolong the electromagnet purpose in useful life.3, permanent magnet can magnetize plunger in advance, and deflection helps the magnetic field that electromagnet produces, with the plunger adhesive to secured core, at one time in mobile contact assembly ordered about down by the return assembly of interlock and follow plunger and be drawn to fixedly contact assembly, maintain electric conducting state.4, this permanent magnetism auxiliary starter earth leakage protective device is safe in utilization, in use security incident can not occur.5, this permanent magnetism auxiliary starter earth leakage protective device is reasonable in design, practical, and product has vast market prospect.
