The utility model relates to the technical field of transmission and distribution, and more specifically relates to an improved high-voltage switchgear handcart, including a car body, a wheel and a guide rail. The wheel is located at the upper end of the car body, the guide rail is sliding connected to the lower end of the wheel, the wheel is connected with a rotating shaft on one side, and the wheel is connected with a connecting rod through the rotating shaft. A connecting through hole is arranged inside the wheel, and a ball is movably connected outside the connecting through hole, a support frame is connected outside the ball, a rubber pad is arranged on the surface of the wheel, and a reset spring is connected inside the rubber pad. By connecting reset springs on the inner side of the wheel, a support limit is formed on the connecting shaft to enhance its connection stability and reduce wear and tear. At the same time, the ball is movably connected on the outer side of the connecting through hole to reduce rolling resistance. In addition, the support springs are connected on both sides of the guide rail to form a clamp on the wheel, which is more adaptable and in the convex block. The traction rope is connected with the connection through hole, and the positioning accuracy is improved.

一种改进型高压开关柜手车
本技术涉及一种高压开关柜,特指一种改进型高压开关柜手车,属于输配电
技术介绍
高压开关柜是指用于电力系统发电、输电、配电、电能转换和消耗中起通断、控制或保护等作用,高压开关柜按作电压等级在3.6kV~550kV的电器产品,高压隔离开关与接地开关、高压负荷开关、高压自动重合与分段器,高压操作机构、高压防爆配电装置和高压开关柜等几大类,手车是可抽出式开关柜中的主要部件,一般有PT手车和开关(断路器)手车两种。手车又叫小车,以开关手车为例,在开关分断的情况下,铺上导轨后可用手将其从开关柜中抽出,以便进行检修或更换。神火集团220kV光明变电站为煤矿供电的35kV高压开关柜存在先天不足,手车不仅笨重、滚动阻力大,而且手车轮子强度低、易损坏,主触头定位不准,倒闸操作时需三个男工才能推动手车,操作极为不便。且因煤矿供电的特殊性,此开关柜无法整体停电更换,只能通过局部改造解决问题,因此设计一种改进型高压开关柜手车很有必要。
