Abstract
The invention relates to a protective circuit for a breaker gap (2), said gap being used to connect a load voltage (UL) to a load (1). The circuit is characterized in that a voltage detection circuit (3) is connected to a detection point (4) on the input side and a detection point on the output side of the breaker gap (2), via detection resistances (R1) said voltage detection circuit (3) being connected to the detection points (4) at high-resistance but in a permanently galvanized manner.
Claims13
A circuit for a circuit-breaker gap (2), by means of which a load voltage (UL) can be applied to a load (1), with a voltage detection circuit (3) being conductively permanently connected via a first detection resistor (R1) to an input-side detection point (4) and via a second detection resistor (R1) to an output-side detection point (4) of the circuit-breaker gap (2),
- characterized
- in that the detection resistors (R1) have the same resistance values, which are greater than 1 megaohm.
