The invention relates to a circuit breaker handcart. The handcart comprises a handcart frame, and a plurality of vacuum circuit breakers and a plurality of mutual inductors which are installed on thehandcart frame. Each vacuum circuit breaker comprises a pole body with a first electrode end and a second electrode end, and a first contact arm electrically connected with the first electrode end ofthe pole body. Each mutual inductor comprises a mutual inductor body with a third electrode end and a fourth electrode end and a second contact arm electrically connected with the third electrode endof the mutual inductor body; the first contact arm and the second contact arm respectively correspond to one of two static contacts in the switch cabinet; the second electrode end of the pole body iselectrically connected with the fourth electrode end of the mutual inductor body, and the pole body is approximately horizontally arranged above the mutual inductor body. Thus, the problems that a mutual inductor in an existing switch cabinet is inconvenient to install and maintain, and the size of the switch cabinet is large are solved.
Description
technical field [0001] The invention relates to the field of switch cabinets, in particular to a circuit breaker handcart. Background technique [0002] Switchgear is a kind of electrical equipment, its main function is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The 10kV metal armored center-mounted handcart switchgear is a medium-voltage switchgear commonly used in the market at present. It has four independent armored compartments, complete functions, and a complete plan. It is the basic switchgear in the power industry. [0003] Such as figure 1 As shown, the circuit breaker handcart in the existing switchgear usually includes a handcart frame 10', a vacuum circuit breaker 11' installed on the handcart frame 10', and a circuit breaker pole 110' of the vacuum circuit breaker 11' It is arranged vertically, and a pair of contact arms 111' of each ci...
