Description
technical field [0001] The invention relates to an operating tool for electrical equipment, in particular to a portable operating device for a handcart of a high-voltage switch cabinet. Background technique [0002] The switch cabinet is composed of two parts: a fixed cabinet and a drawable part (referred to as a handcart). The handcart is the main part of the withdrawable switchgear, generally there are two kinds of PT handcart and switch (circuit breaker) handcart. The handcart is also called a trolley. At present, the body of the switch cabinet handcart is provided with a crank handle, which is connected to the handcart through a screw rod. The operator turns the crank handle to drive the screw rod to rotate, so that the switch cabinet handcart moves forward and backward. move. When the switch is overhauled, the operator needs to manually shake the handcart switch to the test position. For some high-quality switch cabinet handcarts, it is very difficult to rely on manu...
