SU86091A1 - Time delay mechanism for magnetic starters - Google Patents

Description

The known MexaHHSiv-jbi time delays with a liquid damper for magnetic starters, which make the time delay for the starter to go off when voltage is lowered or electric supply voltage is slower ;:, have a complex structure and cannot be r; without a time delay mechanism.

In the proposed mechanism, these drawbacks are eliminated due to the fact that it is made as a separate node attached to the starter that contains a network of two components that interact with each other, and the levers: the service: -; Carrying out the connection between the movable core of the electromagnet and the start-up (lp damper n to block this (the core in the working position of the dwell for a specified time.

The drawing shows an obsessive view of the proposed mechanism.

The cap 14 is simultaneously used for fixing the mounting position of the pei-lining screw n of the piston with the help of the protrusion In p of the spring clamp / 5.

A change in the size of the flow area of the adjustment hole // is achieved by a corresponding rotation of the cap 14, as a result of which Lortsish 6 moves along the adjustment screw 9.

The timing mechanism works as follows.

When the voltage in the power supply network decreases or disappears, the actuator operating coil fails to hold the moving core C and the last, heading; moving under the action of springs and its own weight to the left, pushes through the roller 3 onto the lever 2, abutting the roller 5 into the inclined support) of the eichaga 6. Under the action of the pressure-sensitive roller 5 and inclining against the plane of the support, the lever 6 begins to lift upwards. Due to the fluid damper, the lever movements occur with the necessary slowing down, corresponding to the degree of opening of the retractile hole // in the piston 8. Lifting the lever 6, release the lever 2. At the same time, the movable core is able to move freely and opens the main contacts.

The restarting of the disabled of the nuscatel can be carried out in the same manner, without the time restraint mechanism, i.e., by pressing the start-up buttonpad. Due to the presence of the spring 4, the mech-up time delay is self-returning and does not require manual installation to its original position.

If the duration of the decrease is 1; april surpasses the predetermined time and the BKOBV coil: is supplied with a nominal load; p l-: with L1, the disconnection is not PRO 130Idot; This will exclude the installation of the engine and the engine driven by it.
