Installation and inspection device and method of static contact of distribution cabinet

Abstract

The invention provides a device for installing a static contact of a power distribution cabinet and / or inspecting the installation of the static contact. The device comprises a rack, a walking mechanism, a plurality of hollow positioning rods and a plurality of floating structures, wherein the walking mechanism is used for enabling the rack to move close to or away from the static contact along a prescribed path; the hollow positioning rods are fixedly arranged on the rack, and the direction of the longitudinal axis of the hollow positioning rods is positioned to be approximately parallel to the moving direction of the rack; the floating structures are arranged on the tail ends of the hollow positioning rods and can float approximately along the longitudinal axis of the hollow positioning rods. The relative position of the floating structures is corresponding and the prescribed installation position of the static contact is limited at a pushing position of the rack, and the hollow positioning rods and the corresponding floating structure jointly limit through holes capable of approaching the static contact. The invention further provides a method for installing the static contact or inspecting the installation of the static contact in the power distribution cabinet according to the device.

Description

technical field [0001] The present application relates to the field of power distribution, in particular to an installation and / or inspection device for static contacts of a power distribution cabinet, and a method for installing and / or inspection of static contacts. Background technique [0002] The power distribution cabinet is also called a switch cabinet, which is one of the common power distribution equipment. In the power distribution cabinet, there are usually multiple static contacts fixedly installed, such as six static contacts, while in operation, the moving contacts are installed on the vacuum circuit breaker and approached by the chassis vehicle installed under the circuit breaker. And engage the static contact, or disengage the static contact by moving the chassis. [0003] In the conventional installation of static contacts, the static contacts are usually fixed in place manually with fasteners such as bolts through conventional fastening tools, but this posi...

AI Technical Summary

Problems solved by technology

However, since it uses multiple fixed positioning rods, and is installed by putting the static contact on the rod end and pushing it into place, it may easily cause the static contact to fall during the pushing process, which will affect the installation efficiency

Moreover, the way in which the positioning rod and the static contact sleeved on its end are "head-to-head" with the installation position of the static contact in the contact box during the advancing process may cause damage to the static contact.

Moreover, this method of putting the static contact on the rod end of the positioning rod in advance and then advancing and installing it makes the installation process inconvenient

In addition, such an installation mold cannot be conveniently used to inspect the installation position of the already installed static contact

In addition, the mold only provides guide rails matching the running wheels as a guiding mechanism, and cannot achieve good positioning of the static contact installation

In addition, the installation mold is also easy to cause the frame to slide improperly during the process of pushing or fastening the static contact with bolts, which affects the installation.

In addition, there is no structure or component for checking the shutter mechanism of the static contact
