RTWN type high voltage damping resistor
The RTWN type high voltage damping resistor is fixed the both ends of the high voltage cable powering the ESP chamber. Its task is to protect the cable and the ESP power supply unit against the effects of the surge potential place during the flash-overs in the ESP chamber.
Resistor power 400 W
Resistance 60, 100, 200, 390, 1000 Ω
Length 330 mm
Diameter 105 mm
Weight 4,5 kg
The resistor is provided on its ends with two anti-corona discharge hoods. The hoods have the axial threaded holes of 20 mm and 16 mm diameters for fastening.
UPWN universal high voltage change-over switch and RN-UPWN type manual drive
The UPWN type universal high voltage change-over switch and the RN-UPWN type manual drive of this change-over switch are the devices used in the system of the ESP cable powering to gain the necessary contections between the ESP chamber and the power supply unit, the stand-by unit and the ground bus.
These connections are obtained by the manual shift of the switch movable blades positions of the change-over switch during its powerless ststus. The movable contacts on rotational insulators co-operate with switch immovable blades fixed on the immovable insulator and the earthing switch. The drive is transmitted by means of a gear and a roller chain connected with lines.
The UPWN universal change-over can be applied within the whole span of the voltage generated by the power supply units manufactured in ZWSS BELOS S.A.
High voltage earthing isolator
Our earthing isolator is designed for use in the high voltage power supply line for an electrostatic precipitator. It enables connection between the discharge electrode system and the power supply unit or isolation of the unit and simultaneous earthing of the electrostatic precipitator discharge electrodes. The device is equipped with micro-switches and a locking mechanism for the extreme positions of the switching lever.
High voltage earthing switch
The high voltage earthing switch with the manual drive is applied in the ESP chamber powering system and used for earthig of the chamber when a repair work is carried on. The earthing switch is permitted to work in the temperature of 423°K within the whole span of the voltage generated by the ESP power supply units manufactured in ZWSS BELOS S.A. The manual drive is an integral part of the earthing switch and it is mounted on the plate girder with the heat insulation, while its control made by means of a chain transmission. The manual drive is equipped with a set of limit switches for monitoring the actual position of the switch movable blade.
Supporting insulator
The supporting insulator is used fr the bus lead of the high voltage inside a power switchgear.
