The OCHOBHFJM hard disk of these devices is that. that they do not provide saved protection in the start-up position of the switch.

In the case of the brain, the device has the indicated lack of control due to the shunting of the kunun1K.) 1 relay of the minimum voltage ;, the switch (command switch) by the normally closed contact.

In the drawing there is a picture of the proposed device in cocTosniHir, when the command switch contact is open, and J arx on the clamps (1) and (2) the control cein is missing or so small that the relay (3) of the minimum voltage cannot switch its contacts (4) p (o).

The device is as follows.

If the voltage of the relay is sufficient (3), the contact (4) opens and closes the contact (5). After this, the closure and opening of the contact (6) of the comayoannarate will cause, respectively, the switching off of the motorized contactor contactor (7).

If after the starter is turned on. for example; a key in control cephase to a nan |); a key for releasing a relay (3) is min. 1) voltage; the starter is turned off 1) a: 5 contacts with contact (5). This is also due to a single K1) atK; 1B1) alternate opening) of the contact (8) of the maximum start-up relay. This, although the contact (6) of the command device .4 is closed, the actuator cannot spontaneously turn on the monitor, since the roll-up of the relay (3) is of the minimum voltage, closed with contacts (4) n (G)), the NS will energize and close the contact (5 ).

In order to switch on the starter, it will be necessary first to close the contact (6) of the command of the kin (in order for cat 1) to barely (3) get excited, contact (4) to open, and contact (5) to close, and then close it again.

The resistance (9) limits the current in the iienn control when detecting the katunga of the relay (3) by the contacts (4) and (6).

In order for the circuit to work smoothly, it is necessary that the pap) of dropping the relay (3) of the minimum voltage; |; en is above nan /; enn (r is assigned to the contactor of the actuator, w) - / reverting the relay (3) Connector contactor.

The subject of invention

1. A device for a disassembly control of a magnet starter on a two-wire circuit with a 1-hd.maly-yu-pa1r relay used at the operating point; a maximum current circuit breaker 1), and a single-pole, single-stage single circuit-free switch without a frame; that, in order to maintain shnimnoy protection in the start-up switch, the minimum coil relay coil

shuntiro1 ana through vyklschchagsl 1kumandoapparat) with its normally closed contact.

2. In the device, but p. 1, the use of additional power supply for limiting the current in the control when the probe is tuned to the minimum relay.
