OUTDOOR HIGH-VOLTAGE SWITCHGEAR Russian patent published in 2021 - IPC H02B13/02 

FIELD: electrical engineering.

SUBSTANCE: invention is used in the field of electrical engineering for connecting high-voltage overhead power lines with high-voltage cable power lines. The outdoor high-voltage switchgear contains a housing with compartments, a current transformer, earthing switches and switches, in the upper part of the device there are bushings for connecting to an overhead line. According to the invention, the device contains a high-voltage input compartment, in which a disconnector, a transformer for auxiliary needs and interlocking mechanisms are located, a control compartment, in which the disconnector and earthing switch drives are located, control and signaling elements, a relay protection and automation compartment, an electricity consumption meter, in the compartment high voltage with connection there is a vacuum circuit breaker, current transformers, voltage transformers, an earthing switch, interlocking mechanisms, arresters are installed on the traverse. Pin insulators are used to supply voltage through the bushing insulators to the disconnector, on the upper part of the case there is a signal lamp to indicate the presence of voltage on the 6/10 kV supply feeder. The residual current transformer is located in the compartment of the high-voltage switch, and a high-voltage insulated wire with fluorosiloxane insulation and a barrier layer is used for wiring the circuits as busbars.

EFFECT: invention is aimed at improving the safety and reliability of the device, including during electrical work.
