THE CIRCUIT APPARATUS FOR PROTECTING A PRE-CHARGE RESISTANCE USING AN INTER-LOCK SWITCH |
摘要 |
The present invention relates to a circuit apparatus for protecting a pre-charge resistance using an inter-lock switch, and more particularly, to a circuit apparatus for protecting a pre-charge resistance by controlling a current flowing to a voltage transformer of an electric vehicle using an inter-lock switch and a polyswitch. The present invention provides a circuit apparatus for protecting a pre-charge resistance using an inter-lock switch, including a pre-charge resistance, a pre-charge relay and a main relay placed between a battery of a hybrid electric vehicle and a voltage transformer, wherein the circuit apparatus includes an inter-lock switch which is operated complementarily with the pre-charge relay and is for preventing continuous flow of an overcurrent to the voltage transformer and the resulting damage of the pre-charge resistance. |
