Abstract
The utility model provides a reactor for HVDC change of current valve, it reaches casing down to include coil, iron core, cross -over block, insulating backing plate, female row's terminal, thread bush, go up the casing, the coil becomes the hollow circular cylinder structure for the coiling, and the hollow circular cylinder coils into the tube -shape, and a plurality of iron cores overlap on the coil, and are spaced apart with the cross -over block between each iron core, goes up the casing and is the middle hollow circular cylinder shell body with lower casing, and upper and lower casing assembles with one heart and forms the cavity together, and this cavity is placed in to assembled iron core and coil, insulating backing plate is placed in between iron core and last casing and the lower casing, and the thread bush welds in the coil end, and two female terminals of arranging weld respectively in coil both ends position, four mounting holes cancellations with original casing bottom have reduced the die sinking degree of difficulty the when casing is made, have eliminated the interference to the locating place of casing inside iron core, reduce the die sinking degree of difficulty of casing.
Description
【Technical field】
The utility model is related to a kind of reactor, and in particular to a kind of reactor for high voltage direct current transmission converter valve.
【Background technology】
The fixation that original reactor passes through four screws on lower house with base plate, its drawback is to increase lower house
Die sinking difficulty, affects the putting position of enclosure interior iron core.Meanwhile, iron core is intensive due to putting near casing center position, electricity
Anti- device is normally after operation, and casing center temperature is higher.
【Utility model content】
The purpose of this utility model is the shortcoming for overcoming above-mentioned prior art, there is provided one kind is used for D.C. high voltage transmission
The reactor of converter valve, cancels four installation bolts of former lower house bottom, it is ensured that do not send out position of the iron core in shell cavity
It is raw to interfere.
For achieving the above object, the utility model adopts following scheme：
A kind of reactor for high voltage direct current transmission converter valve, including coil, iron core, cross-over block, insulating pad, mother
Row's terminal, thread bush, upper shell and lower house；
To turn to hollow cylindrical structure, hollow circuit cylinder is coiled into tubular to coil, and multiple iron cores are placed on coil, each iron core
Between be spaced apart with cross-over block, upper shell and lower house are intermediate hollow cylinder shell body, and upper-lower casing is mounted concentrically at one
Rise and form cavity, the iron core and coil for assembling is placed in the cavity；Insulating pad be placed in iron core and upper shell and lower house it
Between, thread bush is welded in coil end, and two busbar terminals are respectively welded at coil both ends position.
Further, upper shell and lower house extend an edge from center, and edge is provided with installing hole, and upper shell is with
Housing is fixedly connected by the bolt in installing hole.
Further, four uniform holes are offered on upper shell and lower house edge.
Further, the cross-over block is wedge shape, and cross-over block is embedded in respectively in upper and lower two end faces of tubular.
The utility model has the advantages that：
The reactor of high voltage direct current transmission converter valve of the present utility model includes coil, iron core, upper shell and lower house, on
Lower house is concentrically assembled to form cavity, and the iron core and coil for assembling is placed in the cavity and fixes, by original housing bottom
Four installing holes in portion are cancelled, and reduce die sinking difficulty when housing is manufactured, and eliminate the putting position to enclosure interior iron core
Interference, reduce housing die sinking difficulty.
Further, upper shell and lower house extend an edge from center, and edge is provided with installing hole, and upper shell is with
Housing is fixedly connected by the bolt in installing hole, and installing hole has the effect of radiating simultaneously, reduces the overall temperature of reactor
Degree, with easy for installation, is simple to manufacture, the characteristics of perfect heat-dissipating.
【Description of the drawings】
Fig. 1 is structural representation of the present utility model；
Fig. 2 is body diagram of the present utility model；
Wherein, 1 be coil, 2 be iron core, 3 be cross-over block, 4 be insulating pad, 5 be busbar terminal, 6 be thread bush, 7
It is lower house, 9- installing holes for upper shell, 8.
【Specific embodiment】
The utility model is described in further detail below in conjunction with the accompanying drawings：
With reference to Fig. 1 and Fig. 2, the reactor of high voltage direct current transmission converter valve described in the utility model includes coil 1, iron core
2nd, cross-over block 3, insulating pad 4, busbar terminal 5, thread bush 6, upper shell 7, lower house 8, coil 1 is hollow circuit cylinder, hollow
Cylinder is coiled into tubular, and iron core 2 is uniformly enclosed within coil 1, is separated with cross-over block 3 between iron core 2, and thread bush 6 is welded and line
1 wire outlet end, the welding of busbar terminal 5 and the outlet of coil 1 are enclosed, the coil for assembling is placed in into 8 shapes of upper shell 7 and lower house
Into cavity in；Upper shell 7 and lower house 8 are hollow circular cavity, and housing to center is extended an edge, set on edge
There are four uniform holes as installing hole 9, upper shell 7 is fixedly connected with lower house 8 by the bolt in installing hole, while having
The effect of radiating.Cross-over block 3 is wedge shape, and cross-over block 3 is embedded in respectively in upper and lower two end faces of tubular.
The utility model is improved on the basis of former reactor, there is provided one kind is changed for D.C. high voltage transmission
The reactor of stream valve, the reactor is modified to former upper-lower casing, by four installation bolts for cancelling former lower house bottom,
To guarantee that position of the iron core in shell cavity does not interfere, an edge is extended to center in upper shell and lower house,
Four uniform through holes are opened on edge, is fixed with floor as installing hole.
