Description

Reliable protection against differences of tension in a network has to correspond to a number of requirements. The neglect any of them leads to considerable deterioration in technical parameters and reduces reliability of system of protection. It is possible to carry to the most important requirements:
— high speed of shutdown of the consumer at increase of tension in a network;
— lack of false operations at hindrances in a network;
— fire safety of the device, the device it has to be made of materials which do not sustain combustion;
— reliability of the mechanism of installation of extreme values which spontaneously do not change;
— an opportunity to change time of a delay of turning on of the relay of the device after elimination of accident in the power supply network.

All above protection against ZUBR D50 overstrain meets the listed requirements.

Speed of shutdown of the connected loading at excess of the set limit of 0,05 pages. This speed has enough to rescue household appliances from the destroying action of a high voltage.

Lack of false operations is realized by means of unique algorithm of operation of the processor. Not considerable distortion of a half wave of tension because of hindrances, will not lead to false shutdown of consumers and at the same time at accident will provide reliability of shutdown.

The case of protection against an overstrain in the ZUBR D50 network is made of the self-fading polycarbonate, reliable powerful plugs, in the device there are no elements which are capable to sustain combustion. Besides, protection is equipped with intellectual system of self-preservation which will disconnect loading at emergence of the increased temperature in the device. The increased temperature can appear owing to excess of admissible power or bad contact in a terminal block.

The choice of limits is realized with use of clock buttons, values remain in non-volatile memory of the processor. The established values cannot independently change, unlike the mechanism of the management realized with use of variable resistors which value can change because of dust content, fluctuations of temperature, humidity.

Flexibility of control of a delay of inclusion is very important. For bulk of household appliances there are enough several seconds, but for refrigerators, freezers, conditioners frequent shutdowns — inclusions are very harmful, it creates emergency conditions at launch of compressors. Delay time for this category of household units has to be 6-10 minutes. What pressure in chambers would manage to be leveled that will allow the compressor to begin work without excess risks. In protection against an overstrain of ZUBR D50 it is possible to establish an inclusion delay from 3 with to 10 min. with a step to 3 pages.

Besides, in this model there is an opportunity to correct the displayed actual tension of a network.

Protection against retension of ZUBR D 50 (in an electroboard on all house), the improved model with thermoprotection

Protection against an overstrain, the raised/lowered tension of a network of 220 volts. The improved model with thermoprotection.

It is intended for installation right after the electric meter on input to the house or the apartment, for protection of all electric devices and household appliances connected in the power supply network.
