Description
Technical field
The utility model relates to power fuse technical field.
Background technology
Install in 35KV transformer station 10KV capacitor many employings capacitor box, due to limited space in cabinet, cannot install on request when fuse is installed; There is overall dimension disunity because of manufacturing firm's design standard difference in capacitor, after changing capacitor, position is improper, so spring does not reach design energy storage state and even cannot install when installing fuse, loses original design function; Spring and pressing plate and capacitor conducting rod loose contact, also can cause connecting portion temperature too high, the spring elastic force that generates heat declined, directly affects result of use.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of high-tension fuse of shunt capacitor, has fuse and disconnects ejection rapidly, support equipment safety, ensure the feature of normal power supply.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of high-tension fuse of shunt capacitor, comprises fuse outer layer insulation pipe, primary insulation pipe, fuse, spring, pressure pad and gland; The upper end inwall of described primary insulation pipe is provided with spring base, described spring to be positioned on spring base and to be provided with pressure pad above, described fuse upper end is fixedly connected with pressure pad with spring center through the hole of spring base, described gland covers the upper end in inner layer pipe, flexible conductor above being connected between pressure pad and the upper contact head bolt of outer tube, the lower end of described fuse and the lower end of primary insulation pipe are strained and fixed, and are connected below flexible conductor between the lower end of fuse and the lower contact bolt of outer tube.
The high-tension fuse of above-mentioned shunt capacitor, described top flexible conductor is connected between pressure pad and upper contact head bolt by the centre bore of gland.
The high-tension fuse of above-mentioned shunt capacitor, described spring base is arranged on the shoulder on the inwall of primary insulation pipe upper end.
The high-tension fuse of above-mentioned shunt capacitor, described fuse is provided with the brace that it can be made to strain, and described brace is provided with fastening bolt.
The beneficial effect adopting technique scheme to produce is: the utility model installs Compress Spring and gland on primary insulation pipe, and fuse is pulled open by Compress Spring in gland inside, can support equipment safety.Solve the restriction in original 10KV shunt capacitor high-tension fuse installation site, angle and direction, avoid the defect of spring rapid fatigue, installation process is more more convenient, spring test and change convenient.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A portion enlarged drawing in Fig. 1.
As shown in the figure: flexible conductor below flexible conductor above the centre bore, 5 of 1 primary insulation pipe, 2 outer layer insulation pipes, 3 glands, 4 glands, 6 upper contact head bolts, 7 pressure pads, 8 springs, 9 spring bases, 10 fuses, 11 braces, 12 times contact bolts, 13.
Embodiment
Contrast Fig. 1-2 uses step to be described further to operation of the present utility model:
A high-tension fuse for shunt capacitor, comprises fuse outer layer insulation pipe 2, primary insulation pipe 1, fuse 10, spring 8, pressure pad 7 and gland 3; The upper end inwall of described primary insulation pipe 1 is provided with spring base 9, described spring 8 is positioned on spring base 9 and above and is provided with pressure pad 7, described fuse 10 upper end is fixedly connected with pressure pad 7 with spring 8 center through the hole of spring base 9, described gland 3 covers in the upper end of inner layer pipe 1, flexible conductor 5 above being connected between pressure pad 7 and the upper contact head bolt 6 of outer tube 2, the lower end of described fuse 10 and the lower end of primary insulation pipe 1 are strained and fixed, and are connected below flexible conductor 13 between the lower end of fuse 10 and the lower contact bolt 12 of outer tube 2.Described top flexible conductor 5 is connected between pressure pad 7 and upper contact head bolt 6 by the centre bore 4 of gland.Described spring base 9 is arranged on the shoulder on the inwall of primary insulation pipe 1 upper end.Described fuse 10 is provided with the brace 11 that it can be made to strain, and described brace 11 is provided with fastening bolt.The using method of the present embodiment: one, take off gland 3, first fuse 10 upper end is inserted from primary insulation pipe 1 lower port, the upper end of fuse 10 is fixedly connected with pressure pad 7 with spring 8 center through the hole of spring base 9, fuse 10 lower end is strained and is strained and fixed with the lower end of primary insulation pipe 1, it is more convenient that brace 11 makes adjustment strain fuse 10, is connected below flexible conductor 13 between the lower end of fuse 10 and the lower contact bolt 12 of outer tube 2.Two, be fixedly connected with pressure pad 7 by the centre bore 4 of one end of top flexible conductor 5 through gland, gland 3 covers in primary insulation pipe 1 upper end, and the other end of top flexible conductor 5 is fixedly connected with upper contact head bolt 6.
