The receiving part of electromechanical devices Decree of the State Committee of Standards Council of Ministers on July 28, 1976 № 1824 deadline for implementing the set with 01.01.1978 Instead of GOST 2.724-68, GOST 2.725-68, ** GOST 2.738-68 ***, GOST 2.747-68 * 4 * edition (October 2000) with Amendment number 1, approved in July 1980 (MIS 11-80) ________________ ** Part n. 9 (refer to coils relays, contactors, magnetic starters). *** As part of subparagraph 7 of Table. 1 (refer to the winding of the electromagnet finder). * 4 of subparagraphs 22, 23 tables (refer to relay coil, contactor, magnetic starter, solenoid, an electromagnet coil selector). 1. This standard establishes a conditional graphical notation is often perceived electromechanical devices (electrical relay, which is often perceived relationship with the executive mechanically, and magnetic starters, contactors and solenoids) * 5 in the schemes operated manually or automated way of products for all industries. ______________ * 5 Legend of the executive parts (contacts) electromechanical devices installed in GOST 2.755-87. Corresponds to the standard CT SEV 712-77. (Revised edition, Alt. № 1). 2. Legend is often perceived electromechanical devices shall correspond with the Table. 1. 3. Dimensions conventional graphic symbols must correspond with the Table. 2. Table 1: Name Designation 1. Coil of the electromechanical device. Note the general term. Conclusions of the coil is allowed to represent one side of the rectangle 2. Coil of the electromechanical devices with a single winding. Note. Sloping line is not allowed to portray, if there is no need to stress that the coil with one winding 3. Coil of the electromechanical device with two windings Note. Allowed to use the following notation 4. Coil of the electromechanical devices with n sub-windings Notes 2-4: 1. Around a rectangle or a rectangle can specify the quantities characterizing the winding, for example, the coil with two windings, the resistance of 200 ohms each 2. If the coil of electromechanical devices with multiple windings to spread the scheme, each winding depicted as follows: coil with two windings of the coil with n windings 5.
