Abstract
The utility model relates to a power supply device, in particular to a switch cabinet bus grounding device. The device comprises a chassis provided with universal wheels; a telescopic support rod is arranged on the chassis; a cross arm is arranged at the upper end of the support rod; grounding probe tubes are uniformly arranged in parallel on the cross arm; grounding probes are arranged at the front ends of the grounding probe tubes; one ends of grounding conductive wires perforate the grounding probe tubes and are connected with the grounding probes, and the other ends of the grounding conductive wires are connected with a grounding bus; when in use, a valve-driven handcart is pushed into a handcart room, the valve is opened, and the handcart backs to a testing position after conforming no voltage via electricity testing; a bracket is opened, mounted on the handcart, and then pushed to an operation position; a grounding part is inserted into a static contact, and the rear end of the grounding part is fixed on the bracket to form an integral grounding manner based on that the static contact protects a baffle plate to drive the handcart; and a light, flexible and reliable support structure is formed by adopting a telescopic and stackable integral mechanical bracket design, the grounding part is an insulation rod inserting ground wire, and can be connected with the bracket to form a whole, so as to ensure reliable grounding.
Description
Technical field
The utility model relates to power supply unit, specifically a kind of safe and reliable, easy for installation, switch cubicle busbar grounding device that ground connection is effective.
Background technology
As everyone knows, the switch cubicle that power supply is now used is the metal-closed switch cubicle of armored, and it has advantages such as compact conformation, easy for installation, reliable in quality; It is the basis that guarantees safety that the switch cubicle bus is implemented ground connection, the maintenance that often need carry out, and present switch cubicle grounding scheme mainly contains following several kinds: the one, adopt conventional earth connection; It is connected on the bus bar side fixed contact; But because the fixed contact present position is special, it is unreliable to articulate, and easyly comes off and misses the danger of bumping; The 2nd, direct hanging earthing conductor on bus, this type of switch cubicle is fully closed, need open bus-bar room, and bus is outer for the complete roasting insulating barrier that covers, and from then on articulate the easy damaged bus insulation, and it is loaded down with trivial details to connect whole process operation; The 3rd, adopt producer that a ground connection handcart is provided, this ground connection handcart is an integral type, difficult, in the process of implementing ground connection, complicated operation, and be prone to injure operating personnel, do not meet on-site actual situations, and cost an arm and a leg.Above-mentioned three kinds of schemes all can't reach the purpose of reliable ground, exist equipment and the great hidden that the person damages, and do not meet State Grid Corporation of China's electric power safety working regulation regulation.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes above-mentioned prior art, and a kind of present employed busbar grounding scheme of having overturned is provided, and adopts the switch cubicle busbar grounding device of new design idea and theory.
The utility model can reach through following measure:
A kind of switch cubicle busbar grounding device; Be provided with the chassis of band universal wheel, the chassis is provided with telescopic pole, and the pole upper end is provided with cross-arm; Cross-arm is provided with the ground connection inserting tube that spacing is identical, be parallel to each other; Ground connection inserting tube front end is respectively equipped with grounded probe, and earth lead one end passes the ground connection inserting tube and is connected with grounded probe, and the other end is connected with earth bus.
When the utility model uses, valve is driven handcart push the handcart chamber, open valve; During through the true no-voltage of electrical verification, handcart falls back on test position, support is opened be loaded on the handcart; Push the service position again, grounded part is inserted in fixed contact, support is fixed in the rear end; Form integral ground and be basis, adopt scalable, as to fold formula whole mechanics support Design with fixed contact protection barrier driving handcart, form light, flexibly, the reliable supporting structure; Grounded part is an insulating bar grafting ground wire, can be connected to form integral body with support, to guarantee reliable ground.
