SU98601A1 - Drive control station for machines with technological contacts - Google Patents

Description

The invention of the invention includes a station controlled by the drive of machines equipped with technological contacts, which closes the process at the HapyJHeHHH and thereby automatically connects the drive electrode.

The station consists of mounted1 (LL in the range of CTa.ibiiOM dust-proof casing of the magnetic starter (contactor) of the three () alternating current, intermediate rec.ce, oste.pennogo resistance. control circuits.

The preference of the station as compared with the similar similar stations, used for the same purposes, is simpler. since it does not have a lower transformer, usually attached to the power supply of control circuits, and an intermediate relay connected to it in parallel with normal-open technological contacts is connected to the auxiliary winding of the magnetic starter (contactor).

which plays po.-ü of the secondary winding of the transformer n 1P5, the process contact circuit is lowered (12-16 at the same time, 1) formed by normally open technological contacts and an intermediate relay, are connected to the supply voltage through the resistance, thanks to practically since the very beginning is sincerely on techno-magnetic contacts, since they switch a small current (about 20 m.t.) at non-voltage OTC TCTBIIH and, besides, de-energization of the circuit of the technological contacts occurs automatically and-when disconnecting n skatel (contactor).

The drawing shows an electric circuit diagram of the proposed control station.

The starting of the engine is performed by pressing the emit -KP button with the VP switch closed. This closes the coil circuit of the magnetic starter L (contactor): the latter is turned on, and its norm; the blocker contact blocker / C closes.

At the same time, under the action of an electromotive force, inductively during the 15th windings of the (additional) winding BEFORE the magnetic actuator (contactor) at a stand of 5k, in a single position, in the chain winding to the intermediate relay RP-

In violation of the technological mode, the technology | 11 15 calls up the closure of one of the techno-technological contacts of the TC.

The engine is restarted by pressing the “start” button. However, if the normal course of the process has not been restored and the process contacts remain closed, the drive will continue to operate only as long as the start button is pressed.
