Description

marker

The four-pin draw-out metering element with three voltage transformers is a withdrawable high-voltage functional unit specifically designed for metal enclosed switchgears with a withdrawable element (e.g. KYN28A-12). Its main function is to integrate three voltage transformers (VTs) to collect, measure and protect three-phase voltage signals in the power system.

This product adopts an insulation cylinder or composite insulation structure made by APG epoxy resin casting technology, which ensures high dielectric strength, as well as excellent moisture resistance and dirt resistance. The trolley frame is equipped with reliable mechanical and electromagnetic interlocking devices to ensure that racking-in and rolling-out operations can only be carried out in a de-energized state, fully complying with the “five lock” safety requirements for power systems. Standardized design and dimensions ensure full interchangeability with the withdrawable circuit breaker trolley; The trolley can be easily pumped into the operating position or pumped out into the control/isolated position, which greatly facilitates periodic inspection, maintenance and replacement of equipment, and is a key component to realize the intelligentization and modularization of the high voltage cabinet.
