PKV/M15M is a new development in the PKV group by SKB EP. PKV/M15M combines the best features of its predecessors, offering a high-performance base and unique functions in a compact design.
The device is designed to measure time, travel, and speed parameters of moving parts of SF6, oil, electromagnetic and vacuum high-voltage circuit breakers up to 35 kV of all types (ABB, AREVA, ALSTOM, SIEMENS, etc.).
PKV/M15M locates the problem area of the object and identifies various defects, such as:
opening or closing operations time delay;
pole time difference;
strong bouncing of contacts;
insufficient contact wipe;
сontact reclosure during circuit breaker opening;
rubbing in the driving gear;
malfunction of the opening buffer (damper);
wear of springs inside the arc extinguish chambers, etc.
There are a lot of peculiarities when taking measurements on circuit breakers. It is easy to register time parameters for any type of circuit breakers, but special transducers are required to obtain travel and speed parameters.
PKV/M15M does not have any measurement transducers in the basic complete set. It provides control of time parameters in the range of 0.1 - 10,000 ms (10 s).
In the expert complete set, for speed and travel parameters control, the device comes with two transducers:
the linear DP12 for measuring the movement of moving parts in high-voltage circuit breakers. Range 1-900 mm. Resolution 0.5 mm. Accuracy ±1 mm;
the angular DP21 for measuring the angle of shaft turn in high-voltage circuit breakers. Measuring range 0-360°. Resolution 0.09°. Accuracy ±0.56°.
the additional complete set (by order) includes the rheostat transducer DP32 for measuring the linear movement of the moving part of a high-voltage circuit breaker up to 20 mm. Required for vacuum circuit breakers. Resolution 0.1 mm. Accuracy ±0.1 mm.
PKV/M15M is complete with attachment devices for the installation of measuring transducers on all types of MV and HV circuit breakers (ABB, AREVA, ALSTOM, SIEMENS, SUSOL, etc.).
One of the significant differences between PKV/M15M and previous models of PKV-group instruments is the implementation of additional types of measurement triggering, which take into account various circumstances during diagnostic:
Triggering by main contacts closing is a universal way of measurement triggering, which facilitates the work and does not require additional settings (measurement time, signal duration, cycle type).
Dry contact triggeringis one of the most popular modes among the personnel servicing circuit breakers, where the Closing and Opening time is normalized by dry contact closing.
At the same time, usual measurement triggering modes are as well implemented:
Local triggering mode (internal) is used when connecting directly to the electrical circuit of a high-voltage circuit breaker. In this mode, the device switches the available operating test current.
Remote triggering mode (external) is used when connecting directly to the electrical circuit of a high-voltage circuit breaker. In this mode, the device waits for the voltage to appear.
The device is equipped with a control module with current of 20 A to control the drives of switching devices both DC and AC, which allows diagnostics in both simple operations and complex cycles, including endurance tests.
Possible to perform complex cycles: O, C, CO, OC, OCO, OCO-C, OCO-CO, as well as setting the operation duration, delay, and pause.
The results of object diagnostics are displayed as data with measured and calculated parameters for each cycle operation (when processing measurement results of complex cycles, the instrument automatically splits the cycle into simple operations).
The results include such data as:
TRAVEL PARAMETERS (full travel, travel to pole contacts closure, wipe, difference of operation in travel, bouncing in travel, overshot, rebound);
TIME PARAMETERS (circuit breaker closing time, circuit breaker opening time, pole closing time, time difference of contacts action, bouncing in time);
SPEED PARAMETERS (opening/closing speed, speed calculation on different sections).
To measure travel and speed parameters, DP12, DP21 (expert complete set) and DP32 (additional complete set) transducers are used.
PKV/M15M is a standalone instrument for diagnostics and presentation of measured numerical data on the display.
The measurement results will be transferred to a mobile device (phone/tablet) special software via Bluetooth or to a PC via USB to a cloud server (software is currently under development).
PKV/M15M is quite simple and easy to operate. The device is built into an ergonomic case, which facilitates the device operation. Its weight and dimensions (weight 1.3 kg / dimensions 250 x 150 x 60 mm) rightfully allow to call it a portable measuring device.
The built-in rechargeable battery of PKV/M15M provides full autonomy. Single charge of the device is sufficient for at least 4 hours of uninterrupted operation.
In addition, the device has a color touchscreen display that makes interacting with the device common and familiar.
The PKV/M15M operates in any climate zone within a wide temperature range of -20°C to +55°C. Thermal insulation protects all sensitive components, preventing any damage caused by overheating, and the IP 54 environmental protection rating allows operation even in rainy conditions.
