Abstract
The invention relates to a novel centrally-arranged switch cabinet grounding device which comprises a handcart and a switch cabinet and is characterized in that a grounding device is respectively arranged at two sides of the lower part of the handcart, and grounding copper bars are arranged on two surfaces of the inner side of the switch cabinet opposite to the grounding devices at the two sides of the lower part of the handcart. The grounding devices comprise thick copper bars, copper belts, fixed brackets and pressure springs, wherein the pressure springs are arranged in the fixed brackets; the bottoms of the fixed brackets are connected with the handcart; the copper belts which are in an isosceles trapezoid are arranged on the fixed brackets; the inner sides of the copper belts are in contact with the pressure springs; the bottoms of the two ends of the copper belts are connected with the body of the handcart; and the thick copper bars which are folded into an arch form are coated outside the copper belts. The invention has the advantage that the two sides of the grounding devices are uniformly stressed symmetrically to perform a guiding function when the handcart moves inwards or outwards, so that the handcart can operate more stably and smoothly in the cabinet. The novel grounding device overcomes the defects and the disadvantages of the traditional grounding device and successfully passes the grounding loop test of the national laboratory.
Description
Technical field
The present invention relates to a kind of switch cubicle earthing device, particularly a kind of novel intermediate switchgear cabinet earthing device.
Background technology
In the present mid-switch cubicle, the handcart body mostly adopts bottom friction earthing mode (seeing figure one) with being connected of system total ground connection.The ground connection that this kind earthing mode has overcome former welding cabinet cooperates difficulty, and shortcomings such as interchangeability difference make mid-switch cubicle ground connection reliability, and continuity strengthens greatly.But in actual use, also found some shortcomings: the ground connection row of cabinet is contained on the median septum of handcart bottom, ground connection row be connected with the total ground connection of cabinet by copper litzendraht wire 20, and switch cubicle is when installation, maintenance, often will extract median septum out, only untie litzendraht wire 20 and could extract out, field operation is very inconvenient, and forget the reduction earth connection easily, bring hidden danger to equipment safety operation; Along with a large amount of utilizations of big capacity switch, switch that 4000A is above or isolation handcart need air blast cooling, generally adopt the handcart bottom to add blower fan, ground connection row's position and blower fan location overlap.Because ground connection comes handcart bottom, contact whether all right, observation not too easily.
Summary of the invention
The objective of the invention is to solve existing the problems referred to above of the earthing device of mid-switch cubicle in the prior art, a kind of novel intermediate switchgear cabinet earthing device is provided.The present invention designs a kind of novel intermediate switchgear cabinet earthing device, comprise handcart, switch cubicle, it is characterized in that: on two avris of the bottom of handcart, an earthing device is arranged respectively, the ground connection copper bar is arranged on the inboard two sides of switch cubicle and the earthing device opposite position on two avris of handcart bottom.Earthing device is made up of thick copper bar, copper belt, fixed support and compression spring, compression spring is positioned at fixed support, support bracket fastened bottom connects handcart, the copper belt that is isosceles trapezoid is arranged on fixed support, inboard inconsistent in the copper belt with compression spring, the bottom, two ends of copper belt connects the handcart car body, is covered with in the copper belt outside and is converted into arc thick copper bar.Advantage of the present invention is that the earthing device both sides are stressed symmetrically, can play guide effect when handcart passes in and out, and makes the operation of handcart in cabinet more stable, smooth and easy.New earthing device has overcome the shortcoming of former earthing device with not enough, has passed through the grounded circuit test of government test chamber smoothly.
Description of drawings
Accompanying drawing 2 is a structural representation of the present invention,
Accompanying drawing 3 is the view that is installed on the handcart of the present invention,
Accompanying drawing 4 is the structural representation of earthing device of the present invention when contacting with the ground connection copper bar,
Below in conjunction with drawings and Examples the present invention is elaborated,
Embodiment
During use, when handcart 1 pushes switch cubicle 2, the earthing device 3 that is installed on two avris of handcart 1 bottom contacts with the ground connection copper bar 4 on the inboard two sides of switch cubicle 2, because the outermost of earthing device 3 is to be converted into arc thick copper bar 5, therefore when entering switch cubicle 2, played guide effect, and owing in the fixed support 1 on earthing device 3 compression spring 8 is arranged, can guarantee the ground connection copper bar 4 on the inboard two sides of the thick copper bar 5 reliable contact-making switch cabinets 2 on the earthing device 3 in the time of in handcart 1 enters switch cubicle 2 fully, guarantee that ground connection is reliable and secure.
