Universal trolley type switch cabinet all-insulation curtain plate locking device

Abstract

The invention belongs to the technical field of electric power, particularly relates to a universal trolley type switch cabinet all-insulation curtain plate locking device, and provides the following scheme for solving the problem that an insulation baffle cannot be locked: the universal trolley type switch cabinet all-insulation curtain plate locking device comprises a first adjusting sleeve and a second adjusting sleeve, two ends of the first adjusting sleeve and two ends of the second adjusting sleeve respectively penetrate through a first L-shaped column and a second L-shaped column; a first synchronous moving mechanism and a second synchronous moving mechanism are arranged in the first adjusting sleeve and the second adjusting sleeve correspondingly, rolling wheels are installed at the bottoms of the two first L-shaped columns and the bottoms of the two second L-shaped columns correspondingly, vehicle plates are welded to the tops between the two sets of first L-shaped columns and the tops between the two sets of second L-shaped columns correspondingly, and fixing blocks are welded to the middles of one sides of the tops of the two vehicle plates correspondingly; lifting blocks are inserted into the two fixing blocks correspondingly, lifting mechanisms are arranged in the two fixing blocks correspondingly, and plug pins are arranged above the two lifting blocks correspondingly. The device is universal, the purpose of locking the insulating curtain plate can be achieved, and potential safety hazards are eliminated.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a fully insulated curtain locking device for a universal trolley-type switch cabinet. Background technique [0002] At present, many high-voltage switchgears in substations do not have insulating baffles to isolate them. , busbar room and cable room are separated, but the baffle is a movable baffle, which is easy to be opened; currently there are two tasks that need to be carried out in the trolley-type switch cabinet, (1) trolley-type switch cabinet B repair; ( 2) In the core phase of the trolley cabinet, the high-voltage isolation curtain in the trolley switch cabinet cannot be locked at this time. When the operator is working in the switch cabinet, if the static contact is charged and there is no reliable isolation measure, there will be extreme There is a great risk of electric shock casualties, so it is far from enough to ensure the safety of work only by placing in...

[0002] At present, many high-voltage switchgears in substations do not have insulating baffles to isolate them. , busbar room and cable room are separated, but the baffle is a movable baffle, which is easy to be opened; currently there are two tasks that need to be carried out in the trolley-type switch cabinet, (1) trolley-type switch cabinet B repair; ( 2) In the core phase of the trolley cabinet, the high-voltage isolation curtain in the trolley switch cabinet cannot be locked at this time. When the operator is working in the switch cabinet, if the static contact is charged and there is no reliable isolation measure, there will be extreme There is a great risk of electric shock casualties, so it is far from enough to ensure the safety of the operation only by placing insulating baffles and manually controlling the high-voltage isolation curtains.
