Abstract

The invention discloses a combined vacuum contactor. The combined vacuum contactor comprises a base plate handcart arranged in a switch cabinet, a vacuum contactor and a fuse on the upper end face of the vacuum contactor, wherein the vacuum contactor is movably connected with a static contact arranged in the switch cabinet; and the base plate handcart is provided with a slide track, and a test prompt position and a connection prompt position which are used for indicating that the base plate handcart is in different electrical connection states. The switch cabinet for power supply and distribution complete equipment is formed by combining the vacuum contactor, the fuse and the base plate handcart, and compared with the traditional fixed installation mode adopted for a fixed vacuum contactor and a fuse in a case type switch cabinet, the invention has the advantages that the switch cabinet with the base plate handcart is provided with obvious functional division and separation, an accident can be prevented from being expanded in time, and the vacuum contactor is extremely convenient to overhaul and maintain. A protection grade is promoted, error operation preventability is improved, routine overhaul (especially in a fault state) is extremely conveniently performed, and spare parts can be quickly replaced.

Description

technical field [0001] The invention relates to a handcart contactor, in particular to a vacuum contactor arranged in a switch cabinet. Background technique [0002] Currently on the market handcart switchgear, if you need to disassemble the current transformer, grounding switch, high-voltage incoming cable and lightning arrester, you often need to disassemble the rear panel of the switchgear body and carry out maintenance at the back. Therefore, when installing the handcart switch cabinet, it cannot be installed against the wall. It must be kept at a distance of about 900mm from the wall for maintenance. Therefore, when used, it occupies a large area and the cost of the power distribution room is high, usually 3 to 3 The 10KV vacuum contactor is fixedly installed in the cabinet, and the traditional fixed vacuum contactor and fuse are also fixedly installed in the box-type switch cabinet. There are no obvious functional partitions and partitions in the cabinet. Poor operabi...
