One, electric cartography is regular
The scale of symbol of character of electric equipment graph that adopts national level provision and become, in order to expresses electric control between systematic principle, function, utility and electric component decorate, join and the graph that install a relation call electric plan. Basically have electric hookup and electric principle graph, electric installation plan.
Electric graph scale must observe the standard of newest and electric cartography that national Bureau of Standards issues. Basically have GB/GT4728—1996~2000 at present " electric diagram uses graphic symbol " , GB7159—1987 " the literal symbol in electric technology makes general rule " , GB4026—1992 " wiring wiring terminal and the identifying that specific wire wire carries and general rule of system of applied letter number " , GB/T6988.3-1997 " hookup and electric cartography, connection table " , GB/T6988.1~4—2002 " electric technology. Still must observe mechanical cartography and the relative standard that build n/arc drafting in addition.
1. Electric component scale is regular
Graph the 1 electric principle that is CW6132 lathe pursues. This machine tool included in the graph the join between component of electric conduction of all and electric component and wiring end points concerns.
Graph 1 CW6132 lathe is electric principle graph
1) condition of the graphic representation that touch a head
Electric component touchs what the graphic representation condition of the head should press this electric equipment to be illogical in electric graph electric state and do not accept power position scale.
Touch a head to be illogical by electromagnetism coil to relay of contactor, electromagnetism scale of the condition when report; Press the condition scale when sufferring outside force effect to switch of pushbutton, journey; Press to low-pressure breaker and switchgroup disconnect condition scale; Hot relay is pressed did not take off buckle condition scale; Speed relay is the condition scale of zero hour by electromotor rotate speed; Accident, reserve with call the police the switch condition scale when be in regular job by equipment; The hand that mark has the many stability such as “OFF” to operate the place moves switch to press batch of condition scale when “OFF” position.
