Description of drawings
Fig. 1 uses for the utility model direct-current transmission converter valve and impacts the equalizing capacitor structural representation;
Wherein: 1 is plug connector; 2 is fuse; 21 is last contact jaw; 3 is insulating cylinder; 31 is inner chamber; 4 is base.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
The utility model direct-current transmission converter valve comprises plug connector 1, fuse 2, insulating cylinder 3 and base 4 with the impact equalizing capacitor.
Plug connector 1 adopts copper material, and its top is provided with a bolt and is used for external connection and plug connector 1 screw lock are in the same place.
Fuse 2 adopts full film medium, and it has contact jaw 21 on the elasticity.
Insulating cylinder 3 is a cylindrical shape, and it adopts poured with epoxy resin to form.Be cast for one with plug connector 1 during these insulating cylinder 3 cast, an end that makes binding post 1 have bolt is exposed to insulating cylinder 3 outsides to make things convenient for wiring, and binding post 1 other end is exposed in the cavity 31 of insulating cylinder 3.
Base 4 is a disc, and its material is an aluminium alloy, which is provided with some through holes.
During installation, at first bottom and the base 4 with fuse 2 passes through bolt together; Then fuse 2 is put into the inner chamber 31 of insulating cylinder 3, the part that the contact jaw 21 of fuse 2 and binding post 1 stretch in the inner chamber 31 contacts, because it has the reliability that certain elasticity can guarantee effectively that contact jaw 21 is connected with binding post 1 to contact jaw 21 for spring structure, fills SF in insulating cylinder 3
6And N
2Mist, then base 4 and insulating cylinder 3 usefulness bolts are carried out fasteningly, base 4 and insulating cylinder 3 joints are placed with sealing ring when fastening, can effectively prevent gas leakage like this.The utility model direct-current transmission converter valve can be fixed on the fixed head by the through hole that bolt passes on the base 4 with impacting equalizing capacitor.
The utility model direct-current transmission converter valve adopts the epoxy resin casting to form with the insulating cylinder 3 that impacts equalizing capacitor, and inner inflatable has good self-gravitation and fire resistance, and fuse 2 adopts the all-film power capacitor structure, has solved office and has put problem.The utility model direct-current transmission converter valve is with after impacting equalizing capacitor employing all-film power capacitor structure, and loss tangent is reduced to 0.00033 of minimum by 0.00052 of original minimum, and office is placed on 66KV less than 5Pc, does not develop in running.
