DEVICE FOR MONITORING BREAKDOWN VOLTAGE OF PROTECTION EQUIPMENT FOR OVERHEAD CONTACT NETWORK SUPPORTS AND MEASURING RAIL-TO-GROUND POTENTIAL ON ELECTRIFIED RAILWAYS Russian patent published in 2024 - IPC G01R31/12 G01R29/00 B61K9/08 

FIELD: measuring equipment.

SUBSTANCE: intelligent monitoring of static breakdown voltage of railway contact network support protection devices. The device contains an autonomous power source connected to a charge control circuit, a high-voltage relay, a computer, a high-voltage bleeder, a current measuring circuit, and an analog-to-digital converter (ADC). The ADC is connected to a computer for a programmable reference voltage source and a high voltage converter controlled by it. From the converter, the test high voltage is supplied through a high voltage relay to the first output terminal for connection to the support protection device and to the high-voltage bleeder. The bleeder output is connected to the input of the ADC connected to the computer. The second output terminal for connection to the support protection device is connected to the ADC through a current measurement circuit. The device additionally includes a wireless communication module, for example, Bluetooth, connected to the computer.

EFFECT: increased level of security, automation and flexibility of measurement settings.
