Description
Technical field
The present invention relates to a kind of manufacture field of threephase switch.
Background technology
Threephase switch is common electronic original part, when with measuring truck to process hardware products, all using threephase switch come
The motor of control instrument car, this threephase switch is typically all two-direction switch, i.e., with it is suitable, fall, stop third gear, be in product
During machining state, operator gets to threephase switch " cis-position ", and motor rotates forward to drive measuring truck to complete adding for product
Work, when a Product processing completes that measuring truck need to be stopped, threephase switch is got to " falling " position by operator, is then switched fast again
To " stopping " position, the electronic function of such measuring truck is stopped at once, and in this course, operator gets to threephase switch " falling "
Position is primarily to offset the inertia that motor is rotated forward, and the down time of shortening measuring truck, otherwise, such as operator is three-phase
Switch is directly switched to " stopping " position from " suitable " position, and motor also needs to rotate forward a period of time under effect of inertia, and operator is only
Motor can be waited to carry out the operation of next product after stopping completely, operating efficiency is have impact on, but use Three-phase
Switch and the motor of measuring truck is controlled in the presence of two obvious shortcomings：First, Three-phase switch is touched by conversion
Point realizes switch, once electric leakage entail dangers to operator, two, when needing stopping motor, operator need to open Three-phase
" falling " position is got in pass, is then quickly switched into " stopping " position again, this action is comparatively laborious, not easy enough, Application No.
87210260 Chinese patent has made useful improvement, discloses a kind of three-phase contactless electronics two-direction switch, it is by switch magnetic
Control device, the switch main controller and switch joystick controller composition of bidirectional triode thyristor combination, so make it is contactless during switch, i.e.,
This two-direction switch will not also touch operator, security is greatly improved once leaking electricity, but this technology still has its deficiency
Place, this switch still have it is suitable, stop, fall third gear, need it is quick stop motor when, operate comparatively laborious.
The content of the invention
The technical problem to be solved in the present invention is that the present situation for being directed to prior art is opened there is provided a kind of safe and reliable three-phase
Close, and this threephase switch is easy to operate.
Technical proposal that the invention solves the above-mentioned problems is：A kind of threephase switch of energy delays time to control, including box body, box body
