The manual drive of the PR-2B type is designed for manual operation of outdoor disconnectors and earthing switches.
The earthing conductor is used to ground parts of the circuit and is capable of withstanding currents under abnormal conditions, such as short circuits, for normal time, but is not designed to carry current under normal operating conditions in the circuit.
The earthing conductor can cause consumers to be disconnected in the event of a short circuit or differential currents by emergency protection devices and residual current devices.
The manual lever actuator type PR-10 is manufactured by DSTU EN 62271-102:2016.
The PR-10 manual lever actuator is designed to switch on and off the load-breaker
or disconnector for voltages up to 10 kV in normal and emergency modes, with fixation
in the switched-on and disconnected positions and locking these positions or only in the disconnected position.
Load-breakers of the VNA series are designed for operation in switchgear cabinets, one-way service chambers and cabinets of complete transformer substations of internal installation for voltage classes up to 10 kV of three-phase alternating current with a frequency of 50 Hz (60 Hz) for systems with grounded and isolated neutral.
Disconnectors of the type RD(Z) are manufactured in accordance with TU U 27.1-37611511-004:2022, DSTU EN 62271-102:2016 and are designed to switch on and off de-energised sections of the electrical circuit under voltage of 35 kV and above, as well as earthing switches that are integral with the disconnectors.
The disconnector type RV (200mm, 250mm) is manufactured in accordance with TU U 27.1-37611511-002:2021, DSTU EN 62271-102 and is designed to create a visible break in three-phase AC circuits with a frequency of 50 Hz and a voltage of 6 (10) kV in the absence of load.
The disconnector type RVZ 10 is designed to create a visible break in three-phase AC circuits with a frequency of 50 Hz and a voltage of 6 (10) kV in the absence of load.
The disconnector is manufactured in accordance with TU U 27.1-37611511-002:2021, DSTU EN 62271-102:2016 and is designed to create a visible break in three-phase AC circuits with a frequency of 50 Hz and a voltage of 10 kV in the absence of line load current.
The RVFZ type disconnector is designed to create a visible break in three-phase AC circuits with a frequency of 50 Hz and a voltage of 6 (10) kV in the absence of load.
RLND(z) disconnectors are manufactured in accordance with TU U 27.1-37611511-003:2021, DSTU EN 62271-102:2016 and are intended
– to create a visible break in the electrical circuit in order to ensure safe maintenance of electrical equipment;
– for switching on and off de-energised sections of a high-voltage circuit under voltage;
– grounding of disconnected sections using stationary earthing devices;
– to switch off and on the no-load current of transformers.
The PRN(z)-10 actuators are designed for manual switching on and off of the main and earthing blades of disconnectors.
