Abstract
Techniques are described for a bypass switch that includes: a switch body having a column; a switch head which is coupled to the column and in which a sliding part is provided; a sliding part which is inserted into the switch head; a driven latch which is inserted into the sliding part and fixed to a driving shaft penetrating therethrough; a driving latch which is coupled to an end of the driving shaft exposed to an outside of the switch head, and which is provided to be driven by a solenoid; a stop coupled to the front of the switch head; a pressure bearing which is inserted into a lower portion of the sliding part and coupled thereto by a bearing pin; an elastic body provided between the sliding part and the switch body; and a rod coupled to an upper portion of the sliding part.
Claims8
A bypass switch for a static synchronous compensator (STATCOM) and a high voltage direct current (HVDC), comprising:
- a switch body including a column;
- a switch head coupled to the column and provided with a sliding part which is vertically slidable;
- the sliding part inserted into the switch head;
- a driven latch inserted into the sliding part and fixed to a driving shaft passing therethrough;
- a driving latch coupled to an end portion of the driving shaft exposed to an outside of the switch head and provided to be driven by a solenoid;
- a stopper coupled to a front side of the switch head to restrict a movement of the driven latch;
- a pressure bearing inserted into a lower portion of the sliding part and coupled thereto through a bearing pin;
- an elastic body provided between the sliding part and the switch body;
- and
- a rod coupled to an upper portion of the sliding part so as to be insulated therefrom by an insulator.
