Even Opening Type Short Circuit Grounding Operation Pole
A short circuit grounding operation pole (even opening) is a device used in electrical systems to safely ground a circuit or busbar section during abnormal conditions such as short circuits. It allows for the connection of a grounding wire to the system, ensuring that fault currents have a direct path to earth, which helps protect personnel and equipment from electrical hazards.

A short circuit grounding operation pole (even opening) is a device used in electrical systems to safely ground a circuit or busbar section during abnormal conditions such as short circuits. It allows for the connection of a grounding wire to the system, ensuring that fault currents have a direct path to earth, which helps protect personnel and equipment from electrical hazards.
Key features and operation details include:
-
: These poles are designed to be compatible with aluminum and copper bus bars and switchgear. The "even opening" likely refers to the mechanical operation of the pole, ensuring a smooth and reliable opening action when disconnecting the grounding connection.
-
Maximum Opening and Grounding Wire Capacity: For example, one model (III type) has a maximum opening length of 32 meters and can accommodate grounding wires with a cross-sectional area up to 50 mm², indicating its suitability for substantial grounding conductors.
-
: The grounding pole is used to create a safe earth connection during short circuit conditions or maintenance operations, preventing dangerous voltage buildup and ensuring that fault currents are safely diverted to ground.
-
: The device can be manually or electrically operated to close (connect) or open (disconnect) the grounding circuit. Safety interlocks prevent accidental operation, and the grounding breaker can be locked in the closed position to prevent unauthorized opening during grounding.
-
: In practical field operations, such poles or devices are used to establish temporary grounding on overhead lines or circuits, protecting workers from accidental contact with live conductors. The grounding pole ensures that any fault current is safely conducted to earth, minimizing the risk of electric shock or equipment damage.
In summary, a short circuit grounding operation pole with even opening is a specialized device designed to safely connect and disconnect grounding conductors during fault conditions or maintenance, providing a controlled and reliable grounding path to enhance electrical safety and system protection.
