The utility model relates to electrical engineering, namely to the structures of single-sided service switchgears with vacuum circuit breakers. The complete switchgear of one-way service contains a compartment for secondary switching, a compartment for busbars, a compartment for current transformers, a compartment for cable connections, located in one housing and separated by partitions. To connect the cable in the cable connection compartment, the connection unit, which is connected directly to the contacts of the transformer by means of an adapter using socket contacts, which consist of a holder, a spring and lamellas, a HySec multifunctional device is built into the device, on the front panel of which there is a control drive and an indication mnemonic diagram. The upper part of the apparatus is made with the function of a switch and consists of a body made of epoxy resin, which contains three vacuum interrupters, and the lower part, made of stainless steel, has the functionality of a three-position disconnector, separator, earthing switch. The technical result of using the utility model is to reduce the size of the complete switchgear. 3 ill.
