[0002] Since there is no reliable isolation baffle for the charged static contact parts in the existing high-voltage switchgear, the safety distance during operation cannot meet the requirements of relevant regulations, so the risk of electric shock increases during the operation of personnel; there is no insulation between the contact holes between the front and rear compartments The baffle may also cause equipment accidents. If the high-voltage switchgear lock fails, the operating personnel may directly push the handcart due to improper operation or excessive force during the switching operation from the inspection position to the test position. into the running position, causing a short circuit fault with the live bus contact

Embodiment Construction
[0010] A trolley for preventing electric shock in a high-voltage switch cabinet includes a base 30 and a first insulating baffle 10 on the base 30 , and rollers 31 are arranged on the base 30 . When the operator works in the high-voltage switchgear and the safety distance between the live parts is not enough, the risk is effectively controlled through the insulating baffle. When setting safety measures, the operator can directly push the cart of the insulating baffle into the high-voltage switchgear, The live contact parts are completely isolated to ensure the safety of operators, which is very convenient and practical.
[0011] A second insulating barrier 20 that can move in the horizontal direction is stacked on one side of the first insulating barrier 10 . Increasing the number of insulation baffles can increase the insulation area, which is to expand the isolation range between operators and dangerous parts, and further ensure the safety of operators.
[0012] The two end...

The invention aims to provide an electric shock prevention cart for a high voltage switch cabinet, which can avoid electric shock risks and power failures in the operation process of an operator. For fulfilling the aim, the technical scheme adopted by the invention is that: the electric shock prevention cart for the high voltage switch cabinet comprises a base and a first insulating barrier on the base; and rollers are arranged on the base. In the technical scheme, the insulating barrier effectively controls the risk that the operator is at an insufficient safety distance away from an electrified part when performing operations in the high voltage switch cabinet; when the operator takes safety measures, the cart with the insulating barrier can be directly pushed into the high voltage switch cabinet to completely isolate the electrified contact part so as to ensure the safety of the operator and electric power operations; and the cart is convenient and practical.
Description
technical field [0001] The invention relates to a cart used for preventing electric shock in a high-voltage switch cabinet, which is mainly used in the electric power industry. Background technique [0002] Since there is no reliable isolation baffle for the charged static contact parts in the existing high-voltage switchgear, the safety distance during operation cannot meet the requirements of relevant regulations, so the risk of electric shock increases during the operation of personnel; there is no insulation between the contact holes between the front and rear compartments The baffle may also cause equipment accidents. If the high-voltage switchgear lock fails, the operating personnel may directly push the handcart due to improper operation or excessive force during the switching operation from the inspection position to the test position. into the running position, causing a short circuit fault with the live bus contact.
