Description

Switch type actuating mechanism operation instrument

Technical Field

The utility model relates to an electric power tech field specifically is a switch type actuating mechanism operation appearance.

Background

The operation method adopted by the switch type actuating mechanism on the market is as follows: the two actuators are in a group, when the first actuating mechanism runs to the open position, the second actuating mechanism is controlled to be opened, and when the second actuating mechanism runs to the open position, the first actuating mechanism is controlled to be closed; when the first executing mechanism runs to the close position, the second executing mechanism is controlled to be closed, and when the second executing mechanism runs to the close position, the first executing mechanism is controlled to be opened. And the process is circulated. At present, a switch type actuating mechanism running instrument is newly manufactured in a trial mode, the switch type actuating mechanism is controlled to run, but a common running instrument can only independently control two actuating mechanisms to run, and the limitation is large. We have therefore proposed a switch-type actuator operator.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a switch type actuating mechanism operation appearance to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: a switch type actuating mechanism running instrument comprises a lead L, the lead L is connected with a normally closed end of a time relay KT2-1, the normally closed end of the time relay KT2-1 is connected with a time relay KT1 through a lead, the lead L is connected with a normally open end of a time relay KT1-1, the normally open end of the time relay KT1-1 is connected with a time relay KT2, the lead L is connected with a normally open and normally closed combined end of a time relay KT1-2, the normally open and normally closed combined end of the time relay KT1-2 is respectively connected with a switch operating contactor KM1 and an open operating contactor KM2, the switch-on running contactor KM1 and the switch-off running contactor KM2 are respectively connected with a switch-in-place micro switch S3 and a switch-in-place micro switch S4, the time relay KT1, the time relay KT2, the off-position microswitch S3 and the on-position microswitch S4 are all connected with a lead N.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: a switch type actuating mechanism running instrument comprises a lead L, the lead L is connected with a normally closed end of a time relay KT2-1, the normally closed end of the time relay KT2-1 is connected with a time relay KT1 through a lead, the lead L is connected with a normally open end of a time relay KT1-1, the normally open end of the time relay KT1-1 is connected with a time relay KT2, the lead L is connected with a normally open and normally closed combined end of a time relay KT1-2, the normally open and normally closed combined end of the time relay KT1-2 is respectively connected with a switch operating contactor KM1 and an open operating contactor KM2, the switch-on running contactor KM1 and the switch-off running contactor KM2 are respectively connected with a switch-in-place micro switch S3 and a switch-in-place micro switch S4, the time relay KT1, the time relay KT2, the off-position microswitch S3 and the on-position microswitch S4 are all connected with a lead N. The time relay KT2-1 and the time relay KT1 are connected in series, the time relay KT1-1 and the time relay KT2 are connected in series, and the time relay KT2-1 and the time relay KT1 are connected in parallel with the time relay KT1-1 and the time relay KT 2.

The working principle is as follows: after the power is on, the operation closing contactor KM1 is attracted, and the executing mechanism is closed to operate; after the in-place closing microswitch S3 is switched off, the actuating mechanism stops;

the time relay KT1 is electrified to start timing, and the time delay T1 and the time T1 are adjustable.

2. After T1 time delay, the time relay KT1-2 normally opens and normally closes the combined end to act, the operation contactor KM2 is opened to suck, and the actuating mechanism is opened to operate; after the switch is in place, the switch-in-place microswitch S4 is switched off, and the actuating mechanism stops;

the time relay KT1-1 is attracted at a normally opened end, the time relay KT2 is electrified, timing is started, and T2 is delayed;

3. after T2 time delay, the normally closed end of the time relay KT2-1 is disconnected, the time relay KT1 loses power, the normally open end of the time relay KT1-1 is disconnected, the time relay KT2 loses power, the normally closed end of the time relay KT2-1 is closed, and the step 1 is repeated.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
