Devices emergency and frequency of automation series URC, Chis, USDM, BWA

Relay URC-3M is a modernized version of the relay WRC-3, has an internal electromagnetic shield that is resistant to magnetic field of industrial frequency on IEC 1000-4-8-93, interference immunity complies with IEC 225-22-1. Relay URC-3M is designed for use in emergency automation of power systems. Functionality The relay is composed of three independent channels and is designed to measure the frequency of the input signal, which is common to all three independent channels. Each of the channels can perform the function of: • ACR - automatic frequency discharge; • CAPV - frequency automatic reclosing; • Analytical grade and frequency dividing automation; • DARS - optional automatic unloading speed reducing frequency; • Automatic-frequency - control increasing frequency. The function of the channel is set by writing the appropriate setpoints for each channel independently. The relay can operate in pulsed or static hold output contacts. Generates a fault signal circuit "dry" contacts. The device control voltage Chis-01, Chis-01M Designed for continuous automatic control circuit voltage windings of transformers of voltages collected in open triangle. The device is intended for mounting on panels and boards control relay halls, relay cabinets and compartments of the switchgear. The device Chis-01 provides the following functions: - measurement of the current effective value of voltage of the input signal; - selection and measurement of the current value of the component of a frequency of 150 Hz; - indication of the current value of the input signal or component at a frequency of 150 Hz (selectable); - triggered, with preset time delay when exceeding the input voltage set point; - triggered, with preset time delay when the reduction component frequency 150 Hz input voltage is below the set point; - fixing the values of the input voltage at the moment of actuation of the device. USDM-01 is a Device for collecting discrete data and the management data transmission via MODBUS RTU. Intended for transmission to the status of discrete signals of the automation object in the monitoring system (control) and run system commands through the built-in relays.

Block bypass / discontinuance BWA-01 The unit is intended for use in circuits RZA-powered secondary circuits of instrument transformers current phases a and C. the Unit is used for non-contact, through a triac, bypass, discontinuance controlled current circuit, if its impedance at a current of 4 And no more than 4 Ohms, and at a current of 50 And not more than 1.5 Ohms. A controlled current circuit can serve as the coils of the electromagnets off actuators type PRBA, PP-61 PP-67, PG-10, or the like. The unit can be used to replace the two relays type RP-321, RP-341, RP-361 and the like. The device functions Application of the unit involves the use of discrete outputs (dry contact) external device relay to control the bypass function/ discontinuance. The unit indicating lights: green led "POWER", which flashes when the output voltage of internal power supplies over 12 In; led red "DESCONTROLADA a" and "DESCONTROLADA WITH that light on the time between the closing of the corresponding triac phase and circuit breaker.
