Description
Technical field
The present invention relates to low-voltage electrical apparatus, more particularly, relate to the three gear shift mechanisms that are used for transfer switching equipment.
Background technology
Transfer switching equipment (being called for short TSE) is mainly used in the switching of two-way power supply.Service position according to the moving contact of TSE can be divided into the TSE of 2 working positions and the TSE of 3 working positions.Among the TSE of 3 working positions, the I position is position of source commonly used; The II position is the stand-by power supply position; 0 position is an open position).Its switching mechanism correspondence is also different.
Fig. 1 is the fundamental diagram of the TSE switching mechanism of existing 3 service positions.
This TSE has 2 moving contacts, and contact has 3 service positions, and the operation by 3 electromagnet realizes its conversion.Its transfer process roughly needs three links.
Fig. 1 is in " I position-position of source commonly used " for TSE.
First link: the M3 electromagnetic actuation, trip link 6 leaves counterclockwise, and triped in " dead point " 8, and contact I disconnects.TSE is transformed into " 0 position-open position ".
Second link: the M1 electromagnetic actuation, L bar 7 is rotated counterclockwise, and drives push rod 4 and moves upward, and at this moment, the M2 electromagnetic actuation ensures that L bar 5 turns clockwise, and till contact II closure, M2 discharges.TSE is transformed into " II position-stand-by power supply position ".
The 3rd link: the adhesive again of M3 electromagnet, the II contact disconnects.At this moment, TSE gets back to " 0 position open position " again.Then, the adhesive again of M1 electromagnet, L bar 7 is rotated counterclockwise, and drives push rod 4 and moves upward, and at this moment, the M2 electromagnet is motionless, and L bar 2 is rotated counterclockwise, and makes contact I closure.TSE gets back to " the I position is used position of source always " again.
TSE finishes the conversion of one-period.
The shortcoming of this series products maximum is that TSE need realize that such switching mechanism link is many, complicated, is unfavorable for improving its reliability of products by 3 magnet when the conversion of finishing one-period.
