Description

A kind of high-pressure vacuum breaker arc-chutes quality testing special stand
Technical field:
The present invention relates to the quality detection technology of electric system electrical equipment, particularly a kind of primary cut-out vacuum interrupter quality testing special stand.
Background technology:
Along with the fast development of electric equipment technology, vacuum switch has obtained widespread use with the superior function of himself in electric system 6.6~35kV field.The core component of vacuum switch is the vacuum interrupter (vacuum bubbles) of sealing.Power circuit stops sending electricity operation, when being short-circuited earth fault, aut.eq. and relay protection would trip, the arc energy that is produced is very big, relies on vacuum interrupter to extinguish the electric arc of huge energy fully.Vacuum interrupter is in keeping and using, and its vacuum has leakage in various degree, and vacuum tightness descends to some extent.Vacuum tightness decline vacuum interrupter to a certain degree drops into operation of power networks and will cause serious electric power accident, and the maintenance of vacuum tightness has determined the quality of vacuum interrupter.Become a crucial job so detect the vacuum tightness of vacuum interrupter.The dynamic/static contact of the indoor conduction of vacuum extinction of normality is closed, carry out the whole bag of tricks quality testing at present, all it must be separated, be installed in the vacuum interrupter on the primary cut-out, because work space is little and the test connection trouble, also need to break away from the electric equipment that other link to each other simultaneously, the quality testing of therefore carrying out vacuum interrupter is very difficult, does not also have the specialized equipment of vacuum circuit breaker arc-chutes quality testing at present.
Summary of the invention:
For solving the problem of primary cut-out vacuum interrupter quality testing difficulty, the invention provides a kind of primary cut-out vacuum interrupter quality testing special stand.This support can not only draw back certain distance with the indoor dynamic/static contact of vacuum extinction, and the big I of this distance is adjusted easily, is fit to carry out the quality testing that all kinds of vacuum interrupters carry out the whole bag of tricks; This support takes insulating material to make supporting leg, has insulating property over the ground, when underproof vacuum interrupter is applied in trial voltage, can guarantee the safety of staff and test apparatus.
The present invention is achieved by the following technical solutions: a kind of primary cut-out vacuum interrupter quality testing special stand comprises that annular metal sheet (1), earth stud (5), two joint supporting legs (10), profile of tooth keeper (9), dop assembly (8), balance pivot (7) etc. constitute primary cut-out vacuum interrupter quality testing special stand.It is characterized in that:
1, upward weld an earth stud (5) in the plane at an annular metal sheet (1), four two joint supporting legs of being made by different materials (10) are simultaneously evenly fixed on the plane down on the annular metal sheet, and are middle with active connection continuous (3).The joint of going up of supporting leg adopts metal material, and the standby hole near diameter 8 millimeter are opened in the lower end is used for installing the lever that has dop, as balance pivot; Be provided with on another relative supporting leg and regulate height profile of tooth keeper (9), match with handle end (12) locating slot of lever, lever handle locating slot and profile of tooth keeper (9) articulate, truck dead lever handle (12) supporting leg joint down is scalable part, with resin or the processing of bakelite insulating material, for adjusting the height of supporting leg, can be made into Collapsible structure;
2, open the aperture of diameter 6 millimeter in the suitable position of lever (12), connect upper and lower two joint arm-ties (11) with straight pin, link to each other with the dop of autocracy, dop just in time blocks the exposed parts of arc-chutes moving contact;
3, dop (6) is made the circle annular with teflon; block arc-chutes moving contact conducting rod; protect its silver coating not to be damaged; the dop outer edge is established a pin-and-hole; connection activity arm-tie, lever, last lower pulling plate, dop constitute a dop assembly (8), are installed on the supporting leg (10) of support; make the indoor dynamic/static contact of vacuum extinction separately, and remain on separated position.
The present invention can make various types of high-pressure vacuum breaker arc-chutes be in detected state, solves the practical problems of primary cut-out vacuum interrupter detection difficult, and is simple in structure, easy to operate.Suitable multiple detection method applies trial voltage to it and detects.
Description of drawings:
Accompanying drawing 1 is a primary cut-out vacuum interrupter quality testing special stand synoptic diagram
Accompanying drawing 2 is mounted in the dop assembly synoptic diagram on the primary cut-out vacuum interrupter quality testing special stand
Accompanying drawing 3 is supporting leg synoptic diagram that have the profile of tooth keeper
Accompanying drawing 4 is that primary cut-out vacuum interrupter quality testing special stand uses synoptic diagram
Embodiment:
Below in conjunction with accompanying drawing utility model is described further:
In accompanying drawing 1, annular metal sheet (1), earth stud (5), two joint supporting legs (10), profile of tooth keeper (9), dop assembly (8), balance pivot (7) etc. constitute primary cut-out vacuum interrupter quality testing special stand.
Outer edge at accompanying drawing 2 centre circles annular dops (6) is provided with a movable straight pin, is connected with lever by two joint arm-ties (11); Be connected between arm-tie and the lever, the connections between the two joint arm-ties, all employing activity straight pin connects; A handle place processing locating slot (12) of lever.
Save supporting leg (1) in accompanying drawing 3, save supporting leg (4), profile of tooth locating slot (2), web member (3), the scalable part of supporting leg (5), lower margin (6) down.
Annular metal sheet in accompanying drawing 4 (1), primary cut-out vacuum interrupter (2), the indoor static contact of vacuum extinction (3) and moving contact (4), earth stud (5), two save supporting legs (10), go up lower pulling plate (11), dop (6), profile of tooth keeper (9), dop assembly (8), balance pivot (7).
4 using method are described in conjunction with the accompanying drawings:
In accompanying drawing 4, primary cut-out vacuum interrupter (2) vertically is placed on the support, and arc-chutes moving contact (4) conducting rod is passed metal ring plate (1) center hole; Put the dop assembly and be in free state, the annular dop of circle (6) be enclosed within on the conducting rod with hand steered firmly, the handle of operating lever (8) is exerted oneself downwards, lever this moment (8) is that the center of circle moves downward with balance pivot (7), enclose annular dop (6) by the stressed inclination of last lower pulling plate (11), the conducting rod that blocks arc-chutes moving contact (4) moves down.Because dop assembly each several part all employing activity pin connects, and guarantees the not other vertically downward strength of moving contact conducting rod.After moving contact (4) and static contact (3) separated suitable distance, lever (8) handle locating slot (12) leaned against on the profile of tooth keeper (9).So far can apply trial voltage on this vacuum interrupter top and carry out quality testing, earth stud (5) is used for testing ground connection, also can be used for applying counter-test voltage.The supporting leg of special stand (10) saves insulation against ground down, can guarantee the safety of staff and test apparatus.
