The PKV/M7 device is intended for in-place control of the oil, gas-insulated, vacuum and electromagnetic switches having up to 4 gaps on a pole and also korotkozamykatel and separators.
Possibilities of the device
- registration in real time of currents of electromagnets of the drive of control of the switching device;
- registration of sag of tension of an operational network;
- measurement of big currents of solenoids by means of current pincers;
- carrying out measurements in simple operations and difficult cycles (In - O, O-B, O-B-O)
- remote control of the device from the personal computer;
- viewing of the measured data (in a tabular and graphic style) on the device screen;
- storage of measurements in archive of the device;
- transfer of archive to the personal computer for creation of the protocol of measurement.
The PKV/M7 device is issued in new modification: PKV/M7 with USB.
The main differences of new PKV/M7 with USB from the previous PKV/M7 version
- carrying out resource tests of the switching device with record of measurements through the set quantity of cycles;
- creation / viewing of passport data of the switching device;
- choice/control/preservation of a template of measurement for simplification and acceleration of the subsequent measurements;
- storage of results of measurements in memory of the device in the form of files which are stored in folders (there is an opportunity to appropriate to folders and files of the name);
- copying of results of measurements on USB Flash the store for the subsequent transfer in memory of the personal computer;
- possibility of measurement of speed to 50 m/s;
- increase in speed of information output (schedules and tables) at the screen after measurement.
The device is equipped with a universal analog entrance for registration of tension or resistance in real time. The regular resistive sensor of the gas-insulated switch can be connected to it that, in total with the incremental sensors of linear and angular movement of DP12 and DP21 which are available in a device set, allows to remove high-speed characteristics for all types of switches according to factory requirements.
The power switchboard of the device possesses characteristics of the control panel the switch: it is possible to set performance of the simple operations "Inclusion" (V), "Shutdown" (O) or the difficult cycles "V-Tzo-au", "O-Tp-V", "O-Tp-V-Tzo-au" and to regulate duration of command impulses and pauses between them. The case is manufactured of shock-resistant polymeric material in the form of an airtight case.
