Abstract
The invention relates to a novel vacuum arc-extinguishing chamber detecting support frame, which consists of a metal annular panel, insulating support legs, an adjustable pointer, a grounding screw bolt, a tension screw rod and a transverse rod with a guide sleeve and is characterized in that a plurality of insulating support legs are arranged on the metal annular panel, the adjustable pointer is arranged on the insulating support legs, and the transverse rod with the guide sleeve is welded on the insulating support legs. When the novel vacuum arc-extinguishing chamber detecting support frame is used, a screw nut is regulated to the lower part of the tension screw rod with millimeter scales, the tension screw rod is inserted into the guide sleeve from bottom to top, the upper end part of the tension screw rod is connected with the lower end of a movable contact rod of a vacuum arc-extinguishing chamber, the pointer arranged on the insulating support legs is regulated to a state of being pointed to the initial position and is fixed, the screw nut is rotatablely regulated according to the scale pointed by the pointer, and a movable contact and a static contact of the vacuum arc-extinguishing chamber are separated for the required distance. The novel vacuum arc-extinguishing chamber detecting support frame has the advantages that the problems of operation instability of the existing high-voltage vacuum circuit breaker arc-extinguishing chamber detecting support frame is solved, the structure is simple, the use is convenient, the pulled distance of a movable contact and a static contact of a vacuum circuit breaker can be intuitively displayed, and the support frame is suitable for the detection of the vacuum degree and the insulation intensity of high-voltage vacuum circuit breaker arc-extinguishing chambers in various types.
Description
Technical field:
The present invention relates to detect the servicing unit of electric equipment, especially can make vacuum interrupter moving contact and fixed contact be in the detection support of setpoint distance according to the detection needs.
Background technology:
High-pressure vacuum breaker is as the important protection in electric power system 6.6～40.5kV field and stop sending electrical control equipment.Its core component is the vacuum interrupter of sealing; The maintenance level of vacuum level of vacuum arc-quenching chamber; Determined whether the performance and the vacuum circuit-breaker of high-pressure vacuum breaker be intact; Therefore changing, all must carry out the detection of power frequency withstand test and vacuum degree to the maintenance of vacuum circuit-breaker, installation and to the vacuum circuit-breaker vacuum interrupter, whether intact to judge its performance.Because the effect of the self-closing power of vacuum interrupter, the moving contact and the fixed contact of the indoor conduction of primary cut-out vacuum extinction of normality are closed, carry out the whole bag of tricks quality testing at present, all must moving contact and fixed contact be separated under the distance of regulation and carry out.The inventor's invention ZL200820069273.1 adopts lever principle that vacuum interrupter moving contact and fixed contact are separated, and exists operation unstable, and the distance of separating is not directly perceived, and problem such as range deviation is bigger, needs further improvement.
Summary of the invention:
In order to overcome the deficiency that existing vacuum interrupter detects support, the present invention improves ZL200820069273.1.Use the pulling force screw rod instead indoor moving contact of vacuum extinction and fixed contact are separated certain distance stably; The pulling force screw rod can rest on any position; That draws back can adjust apart from size very easily; " millimeter " scale is established on surface at the pulling force screw rod, establishes a pointer on the supporting leg that insulating material is processed, and is used for indicating the numerical value that spaces out.
The present invention realizes its goal of the invention through following technical scheme:
A kind of novel evacuated arc control device detect support; Constitute by metal ring panel, isolation leg, settable pointer, earth stud, pulling force screw rod, the cross bar that has a fairlead; Its special sheet is: on the metal ring panel; Some isolation leg are installed, settable pointer is set on the isolation leg, and be welded with the cross bar of tape guide cover.During use; The adjustment nut is to the pulling force screw rod bottom that has " millimeter " scale, and the pulling force screw rod inserts in the fairlead from bottom to top, with pulling force screw rod upper end and vacuum interrupter movable feeler lever lower ends; Pointed original position on the adjustment isolation leg is also fixing; According to the scale of pointed, rotation adjustment nut, separately vacuum interrupter moving contact and fixed contact are to the distance that needs.
The present invention has overcome existing high-pressure vacuum breaker arc control device detection support and has operated unstable problem; Simple in structure; Easy to use; Can intuitively show the distance that vacuum circuit-breaker moving contact and fixed contact draw back, the detection that is fit to various types of high-pressure vacuum breaker arc control device vacuum degrees and dielectric strength is used.
Description of drawings:
Accompanying drawing 1 is that novel evacuated arc control device detect the support sketch map
Accompanying drawing 2 is that novel evacuated arc control device detect the pulling force screw rod sketch map on the support
In the accompanying drawings, the 1st, the metal ring panel, the 2nd, isolation leg, the 3rd, settable pointer, the 4th, earth stud, the 5th, the pulling force screw rod, the 6th, have the cross bar of fairlead, the 7th, adjustment nut, the 8th, right-hand screw line, the 9th, left-handed nut, the 10th, millimeter scale.
Embodiment:
Below in conjunction with accompanying drawing the present invention is further described.
As shown in the figure; A kind of novel evacuated arc control device detect support, by metal ring panel (1), isolation leg (2), settable pointer (3), earth stud (4), pulling force screw rod (5), have the cross bar (6) of fairlead, oppositely adjust nut (7), right-handed thread (8) constitutes.
In accompanying drawing 2, right-handed thread (8) is processed in the upper end of pulling force screw rod, and a millimeter scale (10) is established at the middle part, and left hand thread (9) the reverse adjustment nut (7) of screwing on is processed in the bottom.
In accompanying drawing 1; Metal ring panel (1) is processed with corrosion resistant plate; The cross bar (6) that has fairlead is processed with corrosion resistant plate, and with the welding of the stainless steel parts of isolation leg (2), isolation leg (2) is processed by insulating material and stainless steel; Be installed in metal ring panel (1) below, constitute rack body.Pulling force screw rod (5) is processed with stainless steel, inserts the fairlead of the cross bar (6) that has fairlead from bottom to top, oppositely adjusts nut (7) and processes with brass or other nonferrous materialss.
The present invention vertically is placed on vacuum interrupter on the support, and vacuum interrupter moving contact conducting rod passes the center hole of metal ring panel (1); Be connected with pulling force screw rod (5) upper end right-handed thread (8), the pointer on the adjustment adjustable support leg (2) is to the starting point of millimeter scale; Be rotated counterclockwise reverse adjustment nut (7), vacuum interrupter moving contact and fixed contact separated suitable distance get final product.
