High voltage equipment
High-voltage explosion safe cell RVD-6V
Principal cell electrical schema RVD-6V developed for substitution of cell schemas, which are widely used in mines. Schema is developed on modern relay-semiconductor base with expended functions of previous schema.
Insulation control and management block BUKI
Insulation control and management block BUKI (further referred as block) is intended for remote cell control РВД-6, preliminary control of outgoing connection insulation and protection from emergency modes together with other cell schema elements. Block is intended for substitution of relay control blocks of active cells РВД-6 which are outdated, but technical condition allows prolongation of its life. At the same time capacitors and charging elements of solenoid switching off network are additionally implemented to electronic block besides remote control networks and intermediate relays and minimal protection.
Complex splitting devices KRUV
Complex splitting devices KRUV-6V-UHL5 with electromagnetic or vacuum switch are intended for electric power splitting in networks with voltage of 6 kV with isolated neutral of 50 Hz frequency, electrical installations protection and control of coal mines underground current collectors, having gas and dust hazard. Ex case execution РВ 4ВИа, remote control – РО Иа.
Complex splitting devices KRURN-6А
КРУРН - 6А device is intended for collection and electric power splitting in electrical circuits with voltage 6 kV with isolated neutral of 50 Hz frequency, electrical installations protection and control of coal mines underground current collectors, having gas and dust hazard, on industrial and agricultural enterprises.
Complex splitting devices UK-6
Small-size complex devices UK-6 are used for collection and splitting of electrical power with voltage 6 kV, isolated neutral networks protection and control of coal mines underground current collectors, having gas and dust hazard.
Switches VEV-6Б-16-630.UHL5 three-pole, with integrated spring drive, controlling electromagnets and protection elements are intended for installation into enclosures of normal mining and explosion hazardous complex splitting devices of three-phase alternating current with frequency of 50 Hz with voltage of 6 kV.
Single phase ground shorting direct protection block BNZ
Single phase ground shorting direct protection block BNZ is intended for selective protection from single-phase shorting (leakages) to ground in cable networks with isolated neutral with voltage 6 kV and frequency 50 H.
Vacuum contactor reverser RVV-6/10-400-4U2
Vacuum contactor reverser RVV - 6/10-400-4U2 is intended for control of mine lifting installations with electrical drive with voltage 6/10 kV of three-phase alternating current with frequency 50 or 60 Hz, which are not subject to atmosphere overloads.
