Side plate apparatus used for isolating switch plug-in unit and plug-in unit thereof

Abstract

The invention relates to a side plate apparatus used for isolating switch plug-in unit. The apparatus comprises: a switch side plate (2) and a pedestal side plate (3); the switch side plate (2) is used to be fixed at a side surface of an isolating switch (4) and the pedestal side plate (3) is used to be fixed at a side surface of a pedestal (5); and the switch side plate (2) and the pedestal side plate (3) form a chase mortising structure. Advantages of the invention are as follows: the side plate apparatus ensures that the isolating switch is vertically arranged on the pedestal without inclination; and moreover, wrong installation of the isolating switch can be prevented. In addition, the isolating switch plug-in unit in the invention enables operation personnel to grasp the isolating switch conveniently during the installation process.

Description

technical field [0001] The invention relates to a side plate device, in particular to a side plate device used for an isolating switch insertion unit. Furthermore, the invention also relates to a switch-disconnector plug-in unit having such a side plate arrangement. Background technique [0002] Disconnectors, such as fusible disconnectors, can be combined with an insulating base to form a disconnector plug-in unit. Three or four pairs of terminals are arranged on the base for connection to the circuit. When in use, the operator installs the isolating switch on the base. Once the isolating switch is damaged due to a fault, it only needs to remove the damaged isolating switch from the base and replace it with a new one. This design greatly facilitates the use of isolating switches. However, in the actual operation process, there are still some problems: 1. The dielectric performance of the isolating switch insertion unit may be reduced due to improper installation of the i...

However, in the actual operation process, there are still some problems: 1. The dielectric performance of the disconnector plug-in unit may be reduced due to improper installation of the disconnector and the base

If the isolating switch is placed on the base at an angle, the interlock device on the drive pole side of the base will prevent the insertion of the isolating switch, while the contact pole on the base farthest from the drive pole can be separated from the base. The distance between the bottom surface of the isolating switch and the top surface of the base is inconsistent, resulting in a drop in the rated impulse withstand voltage at too close a distance and causing danger; Installed upside down; 3. Most of the existing isolating switches are designed to be straight and at right angles, which is inconvenient for operators to hold during use.
