Drawer position device of low-voltage switchgear cabinet

Abstract

The invention relates to a drawer position device of a low-voltage switchgear cabinet. The drawer position device comprises a drawer clapboard and a drawer and is characterized in that a pushing mechanism is arranged at the inner side of the drawer, and a position locking button and a position display window are arranged at the outer side of the drawer; the pushing mechanism comprises a bracket and a sliding block, wherein a mounting plate is fixed on the bracket, the sliding block is arranged on the mounting plate, the sliding block is in contact with the position locking button, and the side part of the sliding block is provided with an inclined chute; the mounting plate is provided with a sliding chute, and the upper part of the mounting plate is inserted into a pin board; a fastening screw is arranged in each of the inclined chute and the sliding chute, the fastening screws are connected with the pin board, and a pin board positioning slot is arranged at the bottom of the drawer clapboard; a clamp spring slot is arranged at the side part of the sliding block, and a pushing spring is arranged in the clamp spring slot; a display pole is arranged on the bracket, a reset spring is connected between the display pole and the bracket, and the end part of the display pole is rotatably connected with the mounting plate; and an inclined sliding surface is arranged at the bottom of the display pole, and the inclined sliding surface is in contact with and matched with an inclined block at the bottom of the drawer clapboard. According to the drawer position device, three positions, namely, isolation, test and working of the drawer can be effectively displayed.

Description

technical field [0001] The invention relates to a position device, in particular to a drawer position device of a low-voltage switch cabinet. Background technique [0002] Low-voltage switchgear is one of the most used equipment in power transmission and distribution equipment. In low-voltage switchgear, in order to ensure the reliability of equipment and shorten maintenance time, the drawer-type installation method can effectively solve the problem of low-voltage switchgear. and shorten the maintenance time, because the drawer has strong versatility and good interchangeability, it can be replaced at any time in case of failure. Therefore, most low-voltage switchgears currently adopt this method. There are currently various structures for inserting and withdrawing drawers. Some structures are too complicated, and the reliability is not good. The correctness of the position display cannot be guaranteed. Therefore, a simple structure is required. But it can also clearly displ...

Problems solved by technology

Therefore, most low-voltage switchgears currently adopt this method. There are currently various structures for inserting and withdrawing drawers. Some structures are too complicated, and the reliability is not good. The correctness of the position display cannot be guaranteed. Therefore, a simple structure is required. However, it can clearly display the device of each position. The combination of mechanical and position sensors can effectively display the specific position of the drawer on the panel, so as to avoid accidents caused by misoperation.
