DEVICE FOR MONITORING THE OPERATIONAL SAFETY OF POWER SWITCHES (DIAGNOSTIC APPARATUS)

摘要

A device for monitoring the safety of operation of power switches (diagnosis apparatus), in particular vacuum power switches in medium-voltage switch boards, is disclosed. The device has a microprocessor unit (ME) that consists of microprocessor (M), microprocessor control (MS), and processoriented storage means (SP) and is under the control of the angle pulse direction of rotation recognition device (WD). In conjunction with the conversion of the movement of the moving part of the power switch under the influence of existing operational states, the device determines the available data of the power switches. A device of this kind is useful in medium-voltage switchboards for documenting and forecasting the actual status of power switches.
