High voltage protection interlock system for serviceability

摘要

An interlock system and method are provided for protecting high voltage electrical couplings. The interlock system may control access to the electrical couplings based on the voltage of the electrical couplings. The interlock system may also selectively energize and de-energize the electrical couplings based on the position of a lid.

主权项

1. A terminal block assembly comprising:
a housing defining an interior region, the housing having an access opening into the interior region; a lid having a closed position that closes the access opening and an opened position that exposes the access opening; at least one terminal located within the housing; at least one high voltage wire having a lead that is configured for receipt in the housing to electrically couple the lead to the at least one terminal; and an interlock system comprising:
a lock having a locked position that locks the lid in the closed position and an unlocked position that allows movement of the lid to the opened position; anda controller that commands movement of the lock between the locked position and the unlocked position.
