Abstract
A capacitor switching contactor is described which includes a standard contactor, an auxiliary switch, an input terminal block, an output terminal block, as well as resistance wires disposed between the terminal blocks, on the one hand, and the auxiliary switch, on the other hand. The resistance wires are connected to connecting terminals in chambers of the terminal blocks, and largely accommodated in the housing of the terminal blocks.
Claims4
A capacitor switching contactor, comprising:
- a contactor including main contacts;
- resistance wires;
- an auxiliary switch including auxiliary contacts which lead with respect to the main contacts, each of the auxiliary contacts being connected in series to a respective one of the resistance wires to form a series combination, each series combination being connected, on a phase by phase basis, in parallel with a respective one of the main contacts;
- and
- an input terminal block and an output terminal block, each of the input terminal block and the output terminal block including a respective housing having chambers, the chambers being insulated from one another, each of the chambers having a connecting terminal disposed therein, the connecting terminal being connected to one of the resistance wires brought out from the respective housing of one of the input terminal block and the output terminal block to be connected to the auxiliary switch, a length of the one of the resistance wires being accommodated in the respective housing of the one of the input terminal block and the output terminal, the input terminal block and the output terminal block electrically connecting each series combination to the main contacts.
