Description

TECHNICAL FIELD

[0001] The utility model belongs to the switchgear technical field, more specifically, particularly relates to a kind of with adjustable extraction anti-drop structure's extraction switchgear. BACKGROUND

[0002] Extraction switchgear is a kind of electrical equipment for low-voltage distribution system, and its core feature is that main electrical components (such as circuit breaker, contactor, etc.) can be extracted or inserted as a whole through guide rail or mechanical device, so that maintenance, replacement or testing can be carried out quickly without affecting the operation of other circuits.

[0003] The present application number is CN202110986335.5, which relates to the field of electrical equipment and discloses an extraction switchgear. The cabinet body has multiple cabinet openings on its front face, and the cabinet openings are used to accommodate corresponding drawer cabinets. The cabinet openings are interconnected, and the drawer cabinets form a channel that connects the cabinet openings between the back plate of the cabinet body and the back plate of the drawer cabinets. The top, back and side surfaces of the cabinet body are integrally sealed. The lowermost drawer cabinet of the cabinet body is a pressure relief drawer cabinet that is slidably disposed in the cabinet opening. When a short circuit accident occurs in the extraction switchgear, the gas temperature and pressure in the switchgear will increase. The pressure relief drawer cabinet will slide out of the cabinet body under the action of high-temperature and high-pressure gas, opening the cabinet opening to form a pressure relief passage. In this way, the high-temperature and high-pressure gas accumulated due to the short circuit accident will be quickly discharged, preventing the extraction switchgear from deforming or even exploding.

[0004] Based on the above, when the drawer unit is extracted in the switchgear, the contact area between the drawer unit and the guide rail is small after the drawer unit is completely extracted, and the weight of the drawer unit is large, which can cause the load on the guide rail to be concentrated and the guide rail to deform, affecting the use effect of the entire switchgear.

[0014] This invention, through the adjustment of the anti-detachment mechanism, allows the operator to pull the pull-out operating handle forward. The forward movement of the handle moves the adjusting drive rod forward, which in turn moves the adjusting drive block forward. Under the action of the adjusting drive groove, the adjusting drive block causes two sets of adjusting limit blocks to move in opposite directions. At this point, the two sets of adjusting limit blocks are pulled out of the pull-out adjusting hole, allowing the entire pull-out cabinet to move forward. When the cabinet stops, the operating handle returns to its original position under the action of the adjusting connecting spring, and the two sets of adjusting limit blocks move in opposite directions and insert into the pull-out adjusting hole, thus positioning the cabinet. This achieves adjustable pull-out of the cabinet, facilitating control over the extension length and improving the operator's convenience. This makes the entire switch cabinet more convenient to use and enhances its overall performance.

[0015] This invention, through the design of a pull-out support mechanism, prevents the support trigger plate from being squeezed. The support trigger plate rotates under the action of the pull-out support spring, which in turn drives the support drive gear, which in turn drives the support drive shaft, which in turn drives the support component. This rotation of the support component provides support for the front end of the pull-out cabinet, resulting in more even force distribution on the entire pull-out guide rail. This prevents the pull-out guide rail from being squeezed and deformed, protects it, extends its service life, and improves the overall performance of the switch cabinet. Attached Figure Description
