Abstract
The utility model relates to the installing structure of a DC speed-regulating power supply rectified by a silicon controlled rectifier for a microcomputer. A machine casing of a standard instrument of an electric unit is utilized, the front part of the machine casing is provided with the microcomputer and a system circuit, the middle part of the machine casing is provided with a power semiconductor circuit, the rear part of the machine casing is provided with an under-current relay, a contactor, a transformer, a turning transfer switch and an aviation socket, and digital displays, convertors, speed regulators, start stop apparatuses, jacks, etc. are arranged on a front and a back panels of the machine casing. In the machine casing with smaller volume, multiple functions of all-digital display, multiple-microcomputer communication, status conversion, over current protection, overload protection, under electricity protection, field loss protection, etc. can be realized. The utility model has the advantages of small volume, convenient operation, novel structure and strong functionality of a complete machine.
Description
The utility model belongs to a kind of mounting structure of silicon controlled rectifier microcomputer direct current speed governing power supply.
Silicon controlled rectifier microcomputer direct current speed governing power supply of the prior art, its mounting structure has varied, technology is also ripe, but its existing installation combining form is often not ideal in some application scenario, the selecting for use of parts causes complex structure or volume bigger, can not in a small-sized cabinet, be comprised in machine performance and function aspects in addition, therefore, in use brought some inconvenience.
The purpose of this utility model is, designs a kind of more small-sized silicon controlled rectifier microcomputer direct current speed governing power supply mounting structure.
Silicon controlled rectifier microcomputer direct current speed governing power supply described in the utility model is installed in electrodynamic element combination standard instrument (hereinafter to be referred as " DDZ ") the modified model cabinet, and its mounting structure as shown in drawings.As shown in Figure 1, microcomputer and circuit system 1 are settled in the front portion in cabinet, and power semiconductor circuit 2 is settled at the middle part in the cabinet, and the rear portion in cabinet is mounted with undercurrent relay 3, A.C. contactor 4, transformer 5, rotating change over switch 6 and aviation socket 7; As shown in Figure 2, on the front plate of cabinet, be mounted with digital display 8, be mounted with digital display circuit 9 on the panel in the cabinet, on front plate, also be provided with display converter 10, manual switch 11, speed-regulating potentiometer 12, starting switch 13 and shutdown switch 13 ' etc.; As shown in Figure 3, on the afterbody plate of cabinet, settle rotating change over switch button 6 ', AC fuse 14, dc fuse 15 and aviation socket 7.
Silicon controlled rectifier microcomputer direct current speed governing power supply described in the utility model; on parts, select digital display circuit board for use; fully integrated and modularization digital-to-analogue and power semiconductor circuit; rotating, manual, automatic switchover device; the I/O wiring bind mode of aviation plug formula; whole machine installation in the less DDZ cabinet of volume, and can be realized that digital demonstration, multi-microcomputer communication, manual/rotating switch, show switching, running status switching, overcurrent, transship, owe multiple functions such as electricity, field loss protection.It is little to have volume, easy to operate, novel structure, the functional strong advantage of complete machine.
