Abstract
The utility model relates to a high-voltage cage-type liquid resistance cabinet which is used for starting high-voltage liquid resistance in the field of high-voltage electrical control. A fixed polarplate of each pair of liquid resistance electrodes is fixed in a liquid resistance box through an insulator; a motor drives a belt pulley to rotate for constituting a deceleration transmission mechanism; the belt pulley is connected with a screw rod and drives the screw rod to rotate, a truss is screwed on the screw rod, a movable polar plate is fixed on the truss through the insulator, the screwrod is horizontally arranged in a cabinet body, one end is supported in a bearing in the cabinet body, the other end is arranged in a hole of the belt pulley, the truss and the screw rod are vertically arranged and in threaded fit, and the forward/reversal rotation of the screw rod can lead the truss screwed on screw rod to complete the circulating motion in the horizontal direction. The high-voltage cage-type liquid resistance cabinet uses the screw rod to drive the movable polar plate to operate transversely, which replaces the longitudinal operation of the original movable polar plate, realizes the transverse motion of the polar plate, reduces the requirements on longitudinal space of the mounting environment, is applicable to placement, breaks the technical monopoly that the excessively high soft start equipment environment is difficult to mount on offshore oilfields and the like at abroad and expands the application range of products.
Description
Technical field
The high pressure liquid resistance that the utility model relates in the high-voltage electrical apparatus control technology field starts cabinet, and particularly the resistance of high pressure cage modle liquid starts the structure of the liquid resistance control section of cabinet.
Background technology
At present, known high pressure cage modle liquid resistance starts its liquid resistance part branch of cabinet and mainly is made up of liquid resistance box, liquid resistance extraction electrode, elevating mechanism, reduction gearing mechanism and servomotor etc., three pairs of liquid resistance electrodes of making of the special processed of copper plate are arranged in each liquid resistance box body, wherein a utmost point is fixed in the liquid resistance box, another pole plate is fixed on high-tension insulator on the crane of transmission elevating mechanism (movable plate electrode of three-phase resistance balancedly is fixed on same Jie's crane by insulator respectively), can be driven by servomotor move up and down.The lifting of crane is with being driven by the screw mandrel traction behind reductor by servomotor.But because the pole plate in the liquid resistance box is to be driven by screw mandrel to move up and down, must occupy the certain height space, under some occasion, in oil tanker, owing to be subjected to the restriction of installing space height, cause too high liquid resistance cabinet to install, therefore the resistance of the liquid of the old-fashioned structure of this kind starts cabinet does not have the field of specific (special) requirements to be promoted fully at these.
Summary of the invention
For overcoming the too high problem that is not easy to install of existing liquid resistance cabinet cabinet, goal of the invention of the present utility model is to provide a kind of high pressure cage modle liquid resistance cabinet, not only can realize normal soft start with realization, and can avoid longitudinal space the restriction of product use, the purpose of being convenient to install.
The technical scheme that its technical problem that solves the utility model adopts is: the fixed plate of every pair of liquid resistance electrode is fixed in the liquid resistance box by insulator; The driven by motor belt pulley rotates, and constitutes reduction gearing mechanism; Belt pulley is connected with screw mandrel, and drive screw mandrel rotation, be rotary with capable frame on the screw mandrel, movable plate electrode fixedly is expert at by insulator on the frame, and it is characterized in that: the screw mandrel horizontal device is in cabinet, one end is supported in the bearing in the cabinet, the other end is contained in the hole of belt pulley, and frame is vertical with screw mandrel places for row, screw mandrel and capable frame threaded engagement, can make the capable frame that revolves thereon finish the shuttling movement of horizontal direction by the positive and negative rotation of screw mandrel; The row frame is supported in the bearing in the cabinet, and bearing is pulley in addition, is embedded in the cabinet, and the two ends of the frame of being expert at are installed, and to bear the weight of movable plate electrode, has also served as " orbit " of capable frame simultaneously, makes it even running.The utility model drives movable plate electrode with screw mandrel and laterally moves, and replaces the original vertical operational mode of movable plate electrode, can effectively dwindle the longitudinal size of cabinet, widens the scope of application of product.
The utility model compared with prior art, made full use of the idle space in the equipment, greatly reduced the volume of equipment, effectively reduce the requirement of equipment, be particularly suitable for, as offshore oil platform etc. the very strict occasion of installation dimension to installing space, from starting on effect and the security performance, can substitute the high-voltage solid-state soft start fully, and have the irreplaceable cost performance of these products, greatly reduce investor's cost.
