Description
Technical field
The present invention relates to the switching mechanism in a kind of transfer switching equipment, belong to low voltage switchgear and control appliance technical field.
Background technology
Transfer switching equipment (being called for short TSE) is mainly used in the switching of two-way power supply, powers continuously to guarantee important load.The conversion operations mechanism of tailored version TSE has (I position-position of source commonly used, three service positions based on the electromagnet actuating both at home and abroad at present; O position-open position; II position-stand-by power supply position), this TSE has two moving contacts, and contact has three service positions, and the operation by three electromagnet realizes its conversion.Its transfer process roughly needs three links.
TSE is in " I position-position of source commonly used ".
First link: the M3 electromagnetic actuation, trip link leaves counterclockwise, and " dead point " triped, and position of source contact commonly used disconnects.TSE is transformed into " O position-open position ";
Second link: the M1 electromagnetic actuation, the L bar is rotated counterclockwise, and drives push rod and moves upward, and at this moment, the M2 electromagnetic actuation ensures that the L bar turns clockwise, and till the contact closure of stand-by power supply position, the M2 electromagnet 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 " O position-open position " again.Then, the adhesive again of M1 electromagnet, the L bar is rotated counterclockwise, and drives push rod and moves upward, and at this moment, the M2 electromagnet is motionless, and the L bar is rotated counterclockwise, and makes position of source contact closure commonly used.TSE gets back to " I position-position of source commonly used " again.
Through the action of three links, 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 three magnet when the conversion of finishing one-period.
Summary of the invention
The purpose of this invention is to provide the switching mechanism in a kind of transfer switching equipment, the conversion operations mechanism that solves existing tailored version TSE adopts the switching mechanism link of electromagnet actuating existence many, complicated, be unfavorable for improving the deficiency of reliability of products, realize that by the present invention switching mechanism is simple, the switching motion process is reliable.
The objective of the invention is to be achieved through the following technical solutions, switching mechanism in a kind of transfer switching equipment, comprise contact A, B, it is characterized in that described switching mechanism is made of with the drive disk assembly that is connected between contact separately electronic device, power transmission gear, main shaft, V shaped wheel, V shaped wheel two jaw portions; The initial point portion of V shaped wheel is fixed on the main shaft, and the two ends of main shaft are fixed in the transfer switching equipment, main shaft middle part fixing force transfer gear, and the power transmission gear is connected with motor, and electronic device connects power supply; The traveller of V shaped wheel by its two jaws portion respectively with drive disk assembly in the chute of push rod be connected, the contact of an arm end of sectional wheel and corresponding position is hinged in the drive disk assembly.
Described drive disk assembly is by push rod, sectional wheel, and L type bar constitutes with the connecting rod that is nested with spring; The fulcrum of L type bar and the middle part of sectional wheel are hinged, the traveller of the chute of push rod one end and V shaped wheel one jaw portion is connected, the arc chute that the traveller of the push rod other end is connected with an arm end of L type bar on back and the sectional wheel is connected, another arm end of L type bar is hinged with an end of the connecting rod that is nested with spring, and the other end of connecting rod links to each other with the pedestal of switch.
The switching mechanism that setting of the present invention is made of electronic device, V shaped wheel, V shaped wheel two jaw portions and the drive disk assembly that is connected between contact separately, during use, electronic device is fixed in the transfer switching equipment, the two ends of main shaft place in the axle bed that is fixed on transfer switching equipment, utilize the rotating drive switching mechanism of motor to make two groups of moving contacts of TSE realize closure and disjunction, thereby finish the conversion between three service positions of TSE, the present invention is simple in structure, switching motion process reliability height can be supporting with existing transfer switching equipment.
Description of drawings
