SU128535A1 - Device for measuring time parameters of telecontrol and remote signaling installations - Google Patents

Description

The reliability of the remote control signaling remote control installation (TU-TS) of the temporary distribution system significantly depends on the correctness of the choice and maintenance of 15 certain limits of the main time parameters.

To identify the causes of abnormal operation, installations use devices that provide fast and convenient measurement of these parameters.

The use of an oscilloscope for this purpose is difficult due to the complexity of the oscillography process and the processing time of materials. Devices containing a unit for isolating the parameter under study and an electromilluser for measuring the duration of this parameter are complex and, when used, the process of checking and setting the settings of the control relay requires a lot of time.

In the described device, these drawbacks are eliminated by the fact that the selection block of the system parameter under study is made on 1g, 1de two polarized relays and niaroivor;) back-up distributor.

The device allows O1g; hops the duration of any pulse or pause in the series, the duration of any electric pulse or pause, the duration of the pulses applied to the actuator actuating relay, the duration of the pulses or pauses in the various circuits of the TU-TC and the release time of the slowed-down relays .

A schematic diagram of the device being shown is shown in the drawing.

The device consists of two parts; The unit will be allocated during the operation of the TU-TS unit of the measured time parameter (pulse or pause) and the electromillisecond-timer. measuring the duration of the selected parameter .:

The selection block of the desired parameter consists of a single-stage distributor / reverse stroke, two polarized relays (relay 2 strokes

No. 128535- 2 distributor and 3-dimensional relays), keys 4, 5 and 6 of the stepping finder and set 7, consisting of 25 plug-in sockets.

Power supply of osun1, est1}, or e1CH for direct current from a source device with a device TU-TS.

For the measurement of the measurements, relays 2 and 5 are simultaneously connected in the device TU-TC to the tested installation contact (terminals 8 and 9). In this case, relays 2 and 3 will repeat a series of pulses applied to the contact of the TU-TC installation, to which they are connected.

Pin 10 of relay 3 switches on the device // finder. Pin 12 of relay 2 through the corresponding finder finder and one of the plug sockets of set 7 includes millisecond 13. Key 5 of the step finder and key} 4 measurements choose the character of the measured parameter - impulse or nauza, and the position of the plug in the set jack 7 determines the number of impulse of the imp pause in the series.

When measuring the pause duration, the keys 5 and 14 close the circuit. In this case, the inclusion of step-by-step distribution & an ite / and millisecond 13 will occur during a pause, with 2 n 3 relays released.

When measuring the duration of the impulse, the keys 5 and 14 should be open. Turning on the stepper distributor and the millisecond timer will then pass through the pulse in the pulled-in position of the 2 to 3 relay.

A set of 7 plug-in jacks is used to select a measure of a measured pulse or pause in the series. Each lamella of the distributor circle corresponds to a certain iomer of the plug socket.

When the plug is installed in the socket of a certain number, the millisecond stop meter is switched on on the desired lamella of the step distributor, or, equivalently, at the right moment a series of pulses. Thus, a pulse is applied in a millisecond, equal to the duration of the measured element in a series of pulses.

With key 4, the supply voltage is turned on. Key 6 serves to turn off the distributor or move it to the zero position. Consistently with the finder //, self-interrupting distributor contact 15 is turned on. The zero position of the distributor is signaled by the ignition of the bulb 16.

An inaroaoro | electromagnet inclusion circuit of the distributor eliminates the effect of the timing parameters of the distributor on the measurement results.

Measurement of impuces and power: 5 occurs and the steady state of the distributor. When measuring pulses, the dispenser is installed on the desired llama on the previous pause.

when measuring a pause on an impulse

pause.

The transition to the next lamella occurs after switching off the millisecond. Thus, the measurement accuracy is determined only by the time pairs / meters of pe.ie 3 and the accuracy of the self millesecond detector.
