Abstract
The present utility model relates to an auxiliary switch of high voltage switch equipment. A shell body is provided with an installing plate for a main shaft to pass through, the main shaft is provided with an angle dial which is connected with the main shaft and used for synchronously rotating along with an internal moving contact of the main shaft, the angle dial is provided with angle scale values, the outer side surface of the installing plate, which is corresponding to the angle scale values of the angle dial, is provided with a transparent observation window for observing angle display of the angle dial; and the observation window is provided with indicating identifications for indicating concrete scale values. In the auxiliary switch, the angle dial is arranged below an end face panel, the angle scale values are determined according to the angle scope of the auxiliary switch, the corresponding end face panel is provided with the observation window for observing the angle display, the angle dial is synchronously rotated with the internal moving contact to realize synchronization with internal contact angle values, thus contacting situations of the internal moving contact and a static contact can be realized accurately, and the auxiliary switch can be installed and debugged conveniently.
Description
Technical field
The utility model belongs to the auxiliary switch parts on the high voltage switchgears such as circuit breaker, isolating switch and earthed switch, is specifically related to a kind of auxiliary switch.
Background technology
Auxiliary switch is the vitals in circuit breaker, isolating switch and the earthed switch equipment, is used for separating brake, combined floodgate, interlocking and signal circuit etc., and the installation quality of auxiliary switch directly has influence on the reliability of switch and the safe operation of electrical network.Auxiliary switch links to each other through shaft coupling or connecting rod with high voltage switchgear, because rigging error or machining error, the auxiliary switch after the assembling need satisfy the characteristic in loop through the fine setting initial angle; Auxiliary switch is not all regulated the indication of initial angle both at home and abroad; The experience that depends on installation personnel is regulated, and is high to personnel's technical merit requirement, inefficiency; Simultaneously auxiliary switch contact electrically contacted the also bad control of degree; Cause hidden danger of quality, and for the demanding application scenario of auxiliary switch angular accuracy, traditional auxiliary switch is difficult to reach ideal effect.
The utility model content
The purpose of the utility model provides a kind of auxiliary switch, can't the display switch angle causes initial angle to regulate difficulty and auxiliary switch contact electrically contacted the unmanageable problem of degree to solve existing auxiliary switch.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of auxiliary switch of high voltage switchgear; Comprise housing and be arranged in the main shaft in the housing; Said housing is provided with the mounting panel that supplies main shaft to pass; Main shaft one end connects the interior lateral surface of mounting panel from inside to outside and from the corresponding aperture of mounting panel, passes, and said main shaft is provided with and is connected with main shaft and is used for and angle dial that the inside moving contact of main shaft rotates synchronously, and angle dial is located at enclosure interior and near the medial surface of mounting panel; This angle dial is provided with the angle index value, is provided with the transparent observation window that the angle that is used for the viewing angle dial shows on the lateral surface of said mounting panel in the angle index value place of angle dial; Said observation window is provided with the sign that is used to indicate concrete scale value.
Also be provided with on the corresponding end panels observation window and be used to indicate the contact function sign that shifts to an earlier date closed Earlymake, normally closed, Chang Kai and snap action contact.
The auxiliary switch of the utility model is provided with angle dial below an end panels; Operating characteristics (being the angular range of auxiliary switch) according to auxiliary switch is confirmed the angle index value; And on corresponding end panels, be provided for the observation window that viewing angle shows; Angle dial and inner moving contact rotate synchronously to be realized with the inner contact angle value synchronously, is used for accurately indicating the situation that contacts (contact angle) of inner moving contact and fixed contact, is convenient to the auxiliary switch Installation and Debugging.
Description of drawings
Fig. 1 is the front view of the utility model auxiliary switch;
Fig. 2 is an angle dial end face vertical view.
Embodiment
Below in conjunction with concrete embodiment the utility model is done further introduction.
The structure chart of the utility model high voltage switchgear auxiliary switch embodiment as depicted in figs. 1 and 2; Can know by figure; This auxiliary switch comprises housing 1 and is arranged in the main shaft 2 in the housing; Housing is provided with the mounting panel 6 that supplies main shaft to spread out of; Main shaft 2 is provided with and is connected with main shaft 2 and is used for and angle dial 3 that inner moving contact rotates synchronously, and angle dial 3 is located at enclosure interior and near the medial surface of mounting panel 6, this angle dial is provided with the angle index value; Be provided with the transparent observation window 4 that the angle that is used for the viewing angle dial shows on the lateral surface of mounting panel in the angle index value place of angle dial; Observation window is provided with the fixed pointers arrow sign 5 that is used to indicate concrete scale value, also is provided with the contact function sign 7 that is used for indicating contacts simultaneously on the observation window of this panel, and corresponding can the indication shifts to an earlier date closed Earlymake, normally closed, Chang Kai and snap action contact.
The auxiliary switch viewed window of the utility model is fixedly installed on the mounting panel 6, the initial angle of reflection auxiliary switch.Auxiliary switch angle dial 3 is installed on mounting panel 6 belows; With auxiliary switch main shaft 2 mechanical connections; And rotate synchronously with inner moving contact; During assembling according to Earlymake, normally closed, Chang Kai and wink moving contact the angle value of each contact of connection point on-off status requirement design, and according to the fine-tuning auxiliary switch main shaft 2 of loop characteristic needs, the angular readings through auxiliary switch contact in the observation window 4 can adjust required initial angle easily.
The utility model angle dial 3 can adopt welding to be connected with auxiliary switch main shaft 2, also can connect through transmission mechanism, and this similar conversion belongs to those skilled in the art's conventional techniques means, drops in the protection range of the utility model.
Claims (2)
1. the auxiliary switch of a high voltage switchgear; Comprise housing and be arranged in the main shaft in the housing; Said housing is provided with the mounting panel that supplies main shaft to pass; Main shaft one end connects the interior lateral surface of mounting panel from inside to outside and from the corresponding aperture of mounting panel, passes, and it is characterized in that: said main shaft is provided with and is connected with main shaft and is used for and angle dial that the inside moving contact of main shaft rotates synchronously, and angle dial is located at enclosure interior and near the medial surface of mounting panel; This angle dial is provided with the angle index value, is provided with the transparent observation window that the angle that is used for the viewing angle dial shows on the lateral surface of said mounting panel in the angle index value place of angle dial; Said observation window is provided with the sign that is used to indicate concrete scale value.
