Relay
for the star-delta starting modes (starting relay of the electric motor)
operating voltage 24/220 V AC, indication of mode ON, STAR, DELTA,
the time setting of the STAR mode. POWER SUPPLY, ERV-YU. It is
it is known that for a soft and smooth start of the electric motor, it is necessary to first
turn on according to the STAR scheme and after a certain time, upon reaching the set
of rotation, switch the motor winding to the DELTA mode. Such a switching scheme
ensures a lower starting current, which increases the lifespan of the electric motor and
increases the stability of the entire power supply system.
Switching
the STAR-DELTA modes can of course be performed using a switch, but when
the use of contactors (starters) and starting relay is better to manage this process
automation.
For
the control of such contactors is offered by TENSE starting relay, or as
they are also called, star-delta switching relay – ERV - YU. After
applying operating voltage to contacts A1 - A2 of relay ERV - YU, the STAR output
will connect to contact Faz, the STAR indicator will light up, and the countdown will begin
acceleration interval t1 (0.1 ... 30 s). After the acceleration interval t1, the outputs
STAR will disconnect, the STAR indicator will go out, and the interval will start counting down
pause t2 (15 ms). After the connection interval t2 has elapsed, contacts Faz and
TRIANGLE, the TRIANGLE indicator will light up and the starting relay is in this state,
as long as the alarm is connected to contacts A1 - A2.
