Abstract
The invention discloses an electrohydraulic box used for a high pressure hydraulic resistance which is composed of a liquid storage box for holding the electrolyte, a fixed polar plate arranged in a box body and a dynamic polar plate; the invention is characterized in that the liquid storage box is internally provided with a plurality of cooling ventilating tubes that penetrate the upper box body and the lower box body; a shell which is preserved with a clearance and provided with an air inlet at the bottom part is sheathed on the periphery of the box body; an isolating supporter is arranged between the box body and the shell; the liquid storage box is made of a glass material; the box body for holding the electrolyte is designed to be a structure mode which is provided with the cooling ventilating tubes, and a shell body is additionally arranged outside the box body, therefore, not only the original use functions of the box body are maintained, but also the size of the box body is reduced, thus being capable of greatly reducing the size of the box body for holding the electrolyte and the use amount of the electrolyte; simultaneously conditions are created for the miniaturization of a soft start device of a whole set of high pressure AC electromotor.
Description
Technical field
The present invention relates to the liquid starting drive of a kind of motor, refer in particular to and relate to a kind of electrohydraulic box for high voltage liquid resistor.
Background technology
A kind of electrohydraulic box for high voltage liquid resistor is a vitals of high voltage motor liquid-state step-down soft starting device, and its inside is provided with conductive liquid and moving, fixed electrode.In fact the electrohydraulic box of existing high voltage motor liquid-state step-down soft starting device is exactly the common cylindrical shape or the rectangular box that are welded into by metal or nonmetallic materials, the movable plate electrode supporting with the motor soft start, fixed plate is being set in this casing and is supplying conducting and the electrolyte of cooling usefulness.Because the limitation in existing a kind of electrohydraulic box for high voltage liquid resistor design; Existing above-mentioned body structure demonstrates following defective: along with the long-play of high-voltage AC motor; Place two electrodes of electrolyte constantly to discharge heat energy, therefore can cause the electrolyte in the casing constantly to heat up; Therefore have to bigger with the cabinet design of splendid attire electrolyte, the volume that this can increase casing undoubtedly also can improve cost of manufacture and use cost, also can take bigger accommodation space simultaneously.
Therefore, how to guarantee that the volume that reduces electrohydraulic box just becomes the act of first-selection under the high voltage motor liquid soft starter device operate as normal function prerequisite.
Summary of the invention
The object of the invention: be intended to propose a kind of electrohydraulic box for high voltage liquid resistor, hope that it can reach the basic function of original electrohydraulic box, can reduce the volume of casing simultaneously again widely.
This electrohydraulic box for high voltage liquid resistor is made up of the liquid reserve tank 2 of splendid attire electrolyte 6, fixed plate 7 and the movable plate electrode of being located in the casing 4, it is characterized in that: described liquid reserve tank 2 built-in some perforation casings cooling channel pipe 3 up and down.
The periphery of described liquid reserve tank 2 is being nested with a shell 1 that leaves the gap and be provided with air inlet 8 in the bottom, between liquid reserve tank 2 and shell, is provided with to isolate to support 5.
Described liquid reserve tank 2 is a glass material.
This electrohydraulic box for high voltage liquid resistor according to above technical scheme proposition; Owing to the liquid reserve tank of splendid attire electrolyte is designed to have the version of cooling channel pipe; And increase a shell body in its outside again; Therefore, not only make it keep original function of use, and can reduce volume and the consumption of electrolyte of the casing of splendid attire electrolyte greatly; Obviously this also creates conditions for the miniaturization of a whole set of high voltage motor soft starter device.
Description of drawings
Fig. 1 is an agent structure sketch map of the present invention;
Fig. 2 is the cross sectional representation of Fig. 1.
Among the figure: 1-shell 2-liquid reserve tank 3-cooling channel pipe 4-movable plate electrode 5-isolates support 6-electrolyte 7-fixed plate 8-air inlet.
Embodiment
This electrohydraulic box for high voltage liquid resistor as shown in the figure; It is a kind of inventive improvements to existing electrohydraulic box for high voltage liquid resistor; This improvement is embodied in two places: one of which, and at liquid reserve tank 2 built-in some perforation casings cooling channel pipe 3 up and down of splendid attire electrolyte.
They are two years old; Be nested with a shell 1 that leaves the gap and be provided with air inlet 8 in the bottom in the periphery of the liquid reserve tank 2 of splendid attire electrolyte; Make extraneous cooling air carry out the cooling of appropriateness, guarantee that electrolysis is in the more desirable working temperature through the interlayer between outer case in air inlet 8 accesses and through the 3 pairs of electrolyte that used and heated up through working of cooling channel pipe that are provided with on the liquid reserve tank.
In the actual design utilization, the liquid reserve tank of splendid attire electrolyte can, macromolecular material making nonmetal with glass material or other.
In actual use; The temperature of the electrolyte when working along with motor in the liquid reserve tank can little by little raise; Because the electrohydraulic box of invention design is provided with an air inlet in the bottom of shell; Can Cryogenic air be passed through the space, bottom that air inlet 8 gets between shells and the liquid reserve tank, and get into the cooling channel pipe of up/down perforation simultaneously, the electrolysis that has relative higher temperature in the liquid outlet tank is lowered the temperature; Make this electrolyte be in comparatively suitable working temperature.
