Abstract
The utility model discloses a multipath switching apparatus for an insulation test and the apparatus comprises an insulation plate and a plurality of pairs of conductive fixed contacts arranged on the insulation plate in a spaced manner. Two ends of every pair of conductive fixed contact respectively extend to a surface opposite to the insulation plate. Moving contacts connected with a test power supply are respectively mounted on a side surface of the insulation plate opposite to a position of every conductive fixed contact. An electromagnetic relay is respectively mounted on the other side surface of the insulation plate opposite to a position of every moving contact. The advantages of the multipath switching apparatus are that safe and reliable switching of the multipath insulation test is realized, attracting and separation of the moving contact and the corresponding conductive fixed contact are realized by electrifying forward current and reverse current through a relay iron-core coil to change magnetic field directions.
Description
Technical field
The utility model relates to test unit, especially relates to the Multi-way switching device for Insulation Test.
Background technology
In insulating boot, insulating glove withstand voltage test, a withstand voltage test will be tested many, therefore needs Multi-way switching device.Adopt the high pressure switching modes at present in the multichannel process of the test, during if any defective test product, whole test all will stop, and must pick out underproof test product just and can re-start test more.Each road of the switching device shifter that uses produces mechanical motion by electromagnet or microswitch, hauls the small ball extension with spring and does experiment on the top of the shelf, if when a certain road test product is breakdown, spring hauls small ball and comes off this road disconnection.The deficiency of its existence is: 1, in high-voltage electromagnetic field, electromagnet or microswitch can produce misoperation; 2, when a certain road test product is breakdown, spring hauls small ball and comes off in this road disconnection process, small ball come off very easily other not the small ball on the flash test circuit shake, produce erroneous judgement.
Summary of the invention
The utility model purpose is to provide a kind of safe and reliable Multi-way switching device for Insulation Test.
For achieving the above object, the utility model is taked following technical proposals:
Multi-way switching device for Insulation Test described in the utility model comprises insulcrete, is disposed on many to the conduction stationary contact on described insulcrete, and the two ends of described every pair of conduction stationary contact extend to respectively a surface corresponding to insulcrete; Be respectively arranged with corresponding to each conduction stationary contact position the moving contact that is connected with experiment power supply in a side of insulcrete, be respectively arranged with an electromagnetic relay in the another side of insulcrete corresponding to described each moving contact position.
Described moving contact comprises: the insulation shell of upper shed structure, be arranged on the magnet in described insulation shell, and be provided with conductive gasket at described magnet upper surface, described conductive gasket extends outside the insulation shell upper shed; In the middle part of running through described conductive gasket and magnet, screw is provided with bolt, the lower end of described bolt and insulated conductor electrical connection.
The utility model advantage is to realize the safe and reliable switching to the multichannel Insulation Test, changes by described relay iron coil is passed to forward and reverse electric current the magnetic direction that produces, and realizes adhesive, the disconnection of described moving contact and corresponding conduction stationary contact.
