Abstract
The utility model relates to an electrical control cabinet of a transformer substation, and belongs to equipment special for transformer substations. The electrical control cabinet consists of a cabinet door and a cabinet body, wherein the cabinet door is provided with a voltmeter, an ampere meter, control buttons, indicator lamps, an electrical control cabinet lock and a radiating area; the cabinet body is provided with travel switches and a motor; and air switches, time relays, a programmable logic controller (PLC), contactors, thermal relays, a direct-current power supply, two terminal strips and an electric wire box are arranged in the cabinet body. The electrical control cabinet has the advantages that the structure of the electrical control cabinet is novel, a logic control device, a process control device and a motion control device are connected to the same network by a multistage distributed control system consisting of the PLC, and field control and detection are realized conveniently. Because the electrical control cabinet is provided with a large number of connecting wires, but connecting wire ports are limited, the two terminal strips are used, and the distribution of electric wires is reasonable and attractive. The electrical control cabinet brings convenience to safe and high-efficiency power consumption of users and operators of the transformer substation.
Description
Technical field
The utility model belongs to electric system, refers in particular to a kind of transformer station specialized equipment.
Background technology
Along with the increase of transformer station, the demand of converting equipment is also more and more come greatly.It mainly is embodied as the user provides the rapid build industrial automation control system Software tool monitoring function, general level.Common power transformation switch board can not be realized multilevel distributed control, can't realize on-the-spot control and detection.
Summary of the invention
The utility model provides a kind of transformer station electrical control cabinet, can not realize multilevel distributed control to solve the general control cabinet, can't realize on-the-spot control and the problem of detection.
The technical solution of the utility model is: cabinet door and cabinet are rotationally connected by hinge, travel switch is fixedly connected with the cabinet upper surface, motor is fixedly connected with the cabinet upper surface, reometer is fixedly connected with the cabinet door, voltage table is fixedly connected with the cabinet door, control knob is fixedly connected with the cabinet door, 8 pilot lamp are fixedly connected with the cabinet door, electric control cabinet lock is fixedly connected with the cabinet door, there is radiating area cabinet door below, electric wire box is fixedly connected with cabinet, cabinet is inner with on being divided into, in, lower three parts, air switch one, air switch two, air switch three, the time relay, PCL is fixedly connected with the cabinet internal upper part, contactor one, contactor two, electrothermal relay, direct supply is fixedly connected with middle part in the cabinet, 2 terminal rows are fixedly connected with bottom in the cabinet, contactor one and contactor two interlockings, air switch two and contactor one, contactor two is electrically connected, air switch one and voltage table be in parallel connect with reometer afterwards and the 220v connection jaws that accesses the 24v direct supply, air switch three is electrically connected with PLC, the 24v direct supply is electrically connected with control knob, control knob is electrically connected with the input end of PLC, the output terminal of PLC is electrically connected with 8 pilot lamp, 2 time relays are electrically connected with the input end of PLC, and 2 travel switches are electrically connected with the PLC input end.
The utility model has the advantage of: novel structure, by the multilevel distributed control system that PLC forms, it realizes on-the-spot control and detection easily with logic control device, process controller and motion control device access consolidated network.Because the line that connects is very many, Wiring port is limited, so with two connecting terminal blocks, the electric wire layout is more rationally attractive in appearance.Make things convenient for the efficient electricity consumption of power transformation user and operator safety.

Fig. 2 is inner structure schematic diagram of the present utility model.
Embodiment
Working method of the present utility model
3 air switches of primary power access of 380v, air switch has protective effect to circuit, if electric current is excessive, air switch jumps to closed condition automatically.Air switch two connects contactors, and 2 contactors form interlocking structures, controls the rotating of motor and stops.Contactor two connects electrothermal relay, and electrothermal relay has protective effect to circuit.Electrothermal relay connects motor, if it is excessive to flow through the electric current of motor, can produce very large heat, and electrothermal relay will automatically jump to closed condition and come protection equipment.Then air switch one voltage table in parallel and series current table access the connection jaws of the 220v of 24v power supply.Air switch three connects PLC, and the 24v power supply connects control knob, and control knob connects the input end of PLC, and the output terminal of PLC connects pilot lamp.Control knob is controlled pilot lamp by PLC.The 24v power supply is time relay power supply, and the time relay connects the input end of PLC, and the time relay is realized the time control action.The 24v power supply is travel switch power supply, and travel switch connects the PLC input end, the motion of going to control circuit and mechanism by the change of the opening and closing state of make and break contact.Because the line that connects is very many, Wiring port is limited, so with two connecting terminal blocks, realize that the electric wire layout is more rationally attractive in appearance.PLC realizes the overall control effect by programming.
