Motorized disconnector actuator PD-14
PD-14 type actuator is designed for electromotive operation of main legs and earthing switches of disconnectors with voltage from 35 to 220 kV, rated current up to 2000A, when installed outdoors, as well as from 10 to 110 kV for operation indoors. The drives are manufactured in accordance with GOST 689-90 in the version UHL category 1 according to GOST 15150-69 and GOST 15543-89.
Structurally, the drive is made in the form of blocks containing the gearbox part (BR) and control and signaling units (CU).
The PD-14 actuator consists of the following main parts:
- a cabinet with a rotary panel,
- electric motor with gearbox,
- manual operation blocking mechanism,
- switching device KSAM12.
The PD-14 actuators for operation of the main blades and actuators for operation of the earthing switches have the same design. There is a red stripe on the outside of the earthing switch actuators door.
The cabinet is a prefabricated construction made of stainless steel profiles, additionally sealed with silicone sealant. The cabinet design provides access to control and signaling devices, gearmotor, terminal clamps from three sides: through the door and through removable side covers.
The side covers are fixed to the cabinet by means of nuts. By removing the side covers, the terminal clamps and gearbox gears can be accessed. The inner surface of the door and covers is sealed with silicon-organic rubber, which protects the internal volume of the cabinet from dust and moisture when closed.
The door is attached to the cabinet by means of hinged hinges, which allow the door to open to an angle of no more than 170°.
At the bottom of the cabinet installed sealed cable glands, designed to seal cables with a diameter of 18 to 25 mm. When cables with a smaller diameter are installed, it is necessary to increase the cable diameter by wrapping a PVC insulating tape on it at the cable entry section.
Control units (CU) are designed for remote control of PD-14 actuators during phase-by-phase and three-phase operation of disconnectors. CUs can be installed both indoors and outdoors.
The cabinet is a prefabricated structure made of stainless steel profiles, additionally sealed with silicone sealant. The cabinet design provides access to control and signaling devices, terminal clamps through the door. The inner surface of the door has a seal in the form of silicon organic rubber, which provides protection of the internal volume of the cabinet from dust and rain when closed. The door is attached to the cabinet with hinges that allow the door to open to an angle of up to 170°. The door has a lock that can be locked with a special key. A padlock can be installed in the lock sleeve.
