Background technology
High voltage isolator is important device for switching in power plant and the transformer station's electrical system, need and the supporting use of primary cut-out, its major function is: guarantee High-Voltage Electrical Appliances and the safety of device when service work, play isolation voltage, can not with cut off, drop into load current and cut-off short circuit current, only can be used for not producing some handover operation of powerful electric arc, that is to say that it does not have the arc extinguishing function; Be divided into by the infield difference, formula outside formula and the room is divided into by the insulation column number within doors, open side type, and queen post and three pillar type, each electric pressure has optional equipment.Also the part that needs in the high voltage distribution installation to have a power failure can be isolated reliably with live part, to guarantee the safety of service work.Existing fixed contact exists the hypodynamic phenomenon of clamping, has potential safety hazard, thus may be accidents caused, threaten production safety.
The utility model content
For addressing the above problem, the utility model provides a kind of fuse disconnecting switch with single-phase fixed contact group, and technical scheme is as follows.
A kind of fuse disconnecting switch is with single-phase fixed contact group, comprise single-phase insulation board 1, it is characterized in that: described a kind of fuse disconnecting switch comprises also that with single-phase fixed contact group an end is formed with the contact 2 that bridle 21, an end are formed with connecting plate 22, be arranged at described bridle 21 the outside, play the spacing ring spring 3 of position-limiting action; Described contact 2 quantity are two, are arranged on the described single-phase insulation board 1; Two sidewalls of described bridle 21 form the plug-in strip slot; The plug-in strip slot of described two contacts 2 is located along the same line.
Thus, by two contacts and single-phase insulation board, improve the compatible degree that closes a floodgate, strengthen the contact pressure of fixed contact by the limit function of ring spring.
A kind of fuse disconnecting switch according to claim 1 is with single-phase fixed contact group, and it is characterized in that: described single-phase insulation board 1 bottom is provided with insulation column 4.
Thus, guarantee the insulation distance between major loop and the fixed contact, improve fail safe.
A kind of fuse disconnecting switch according to claim 1 is with single-phase fixed contact group, and it is characterized in that: described single-phase insulation board one end is provided with end of incoming cables stroma 5, is formed with the lightning rod installing hole on the stroma of described end of incoming cables.
Thus, can lightning protection be installed at single-phase insulation board, improve reliability.
A kind of fuse disconnecting switch according to claim 1 is with single-phase fixed contact group, and it is characterized in that: described ring spring 3 one ends are arranged on the single-phase insulation board 1.
Thus, fixing ring spring.
A kind of fuse disconnecting switch according to claim 1 is with single-phase fixed contact group, and it is characterized in that: described contact 2 one ends are formed with 2-4 bridle 21.
Thus, can improve the intensity of pressure of contact.
A kind of fuse disconnecting switch according to claim 1 is with single-phase fixed contact group, and it is characterized in that: the bottom of described bridle 21 is formed with width greater than the reinforced seat 211 of plug-in strip slot.
Thus, can conveniently install and further strengthen contact intensity.
A kind of fuse disconnecting switch according to claim 1 is with single-phase fixed contact group, and it is characterized in that: the top of described bridle 21 is formed with oblique guide plate 212.
Thus, it is more smooth and easy plug-in strip to be inserted.
