MOBILE DEVICE FOR MONITORING 8E123M RELAY IN NON-STATIONARY CONDITIONS DURING PERIODIC TESTS Russian patent published in 2018 - IPC G01M7/02 G05B23/02 

FIELD: testing equipment.

SUBSTANCE: invention relates to testing equipment, in particular to relay monitoring devices, and can be used for measuring and monitoring the parameters of electromagnetic relays 8E123M under non-stationary conditions during periodic tests using different portable measuring devices. Essence of the claimed technical solution lies in the fact that the mobile monitoring device of relay 8E123M contains two portable direct current sources SPS-3610, measuring wires, an indicator light connected to the circuit in series with the relay contacts, while a remote control panel is additionally provided, which has a board on the front panel with six spring petal-type terminal-sockets for the relay, six single-pole sockets for connecting direct current sources and various measuring devices, toggle switch, functional color marking of the front panel elements of the remote control, carrying handle on the side face, while the signal lamp is placed on the front panel of the remote control, single-pole plugs are soldered at the ends of the measuring wires, relays are inserted into the board and reliably fixed by means of spring terminal-sockets, plugs are inserted into the sockets and securely fixed due to the special connecting design of plugs and sockets.

EFFECT: technical result is to increase the accurateness and reliability of the measurement due to the rigid fixation of the relay in the board by means of spring terminal-sockets in the board, due to the safety of connection of measuring devices by rigid fixing of plugs of wires in single-pole sockets of the remote control panel, essential simplification, reduction of time for measuring relay parameters, reliability and simplicity of design, transportation convenience, small size and light weight of the remote control.
