A kind of anti-mis-collision two-way insulation isolation stop car for substation

Abstract

The invention relates to an anti-miss-collision bidirectional insulated isolation stopper vehicle for a transformer station. A bottom framework of the anti-miss-collision bidirectional insulated isolation stopper vehicle is a square framework. Two sides of a middle part of the bottom framework are symmetrically fixed with vertical caution racks via support rods at the two sides. An upper end of each caution rack is coaxially provided with an alarm. A plurality of caution boards are horizontally fixed between the two caution racks. A lateral side of a middle part of each of the two caution rack is fixedly provided with a U-shaped horizontal caution crosspiece which is arched externally, and the U-shaped horizontal caution crosspieces are in mirror symmetry. An external edge of each caution crosspiece extends out of the bottom framework, and each caution crosspiece is hinged with the caution racks through hinged support pipes. The caution boards which are horizontally fixed on the caution racks of the isolation stopper vehicle alert operational personnel by words, the caution crosspieces are isolated in a front-and-back physical manner, and the caution crosspieces give the alarm via the alarms when being touched by external matters, so that accidents of large area blackout due to maloperation and error touchness by the operational personnel are greatly reduced, and human casualty accidents due to accidental collision of live-line equipment are greatly reduced.

Description

technical field [0001] The invention belongs to the field of substations, and relates to substation maintenance and maintenance auxiliary devices, in particular to a mis-collision-proof two-way insulation barrier car for substations. Background technique [0002] When performing primary equipment maintenance and handling defects in substations, it is almost always carried out when the bus side or line side in the switch cabinet is charged, and the only safety measure to prevent accidental touch is the isolation baffle. However, when the isolation baffle is damaged or abnormal, there will be a safety hazard that maintenance operators will accidentally touch the operating equipment, which will easily cause personal injury and death and large-scale power outages. [0003] Especially in the maintenance of 35kV substations, most of the 35kV equipment is an indoor integral switchgear, and the strokes of some switches, auxiliary contacts such as knife switches are located in the sw...

AI Technical Summary

Problems solved by technology

The existing problem is: due to the aging of equipment and defects in the manufacturing process of some switch cabinets, the isolation baffle between the maintenance personnel and the live contact cannot meet the operation requirements, and there is a major safety hazard of accidentally touching the live equipment, which is likely to cause personal injury. Casualties and large-scale power outages
