The intelligent starting box for the motor comprises a cabinet, wherein a power converting module is arranged in the cabinet; thyristors are arranged between an inlet end and an outlet end; a bypass contactor is respectively straddled at each of the two ends of each of the thyristors; an LED (Light Emitting Diode) control panel displaying Chinese characters is arranged on a front side of the cabinet; and the LED control panel is connected with the power converting module in the cabinet through a driving circuit board. The intelligent starting box for the motor has the advantages of simpleness in operation and convenience in maintenance.

Description

Intelligent motor starting box

Technical field

The utility model relates to high-voltage motor start-up control field, is specifically related to a kind of intelligent electric motor starting case.

Background technology

In the electrical control field; Motor starting device plays an important role; The electric motor starting case is exactly, and generally all to be electric component that the control multiple electric motors is used with a control circuit, prior motor starting drive that multiple electric components such as circuit breaker, thermal relay, contactor, the time relay and binding post are overlapped to form control motor start-up and operation install concentratedly in a cabinet that is called as " control cubicle " with the form of loose mail, at mechanical fields such as oil field, mines important use arranged all.

Application number is that 200520087332.4 Chinese utility model patent discloses a kind of electrical machine energy-saving control cubicle; It is made up of cabinet, intelligent microprocessor controller, current transformer and contactor components and parts; Be that cabinet is a rectangle; Be provided with intelligent microprocessor, contactor and components and parts on the inner panel in cabinet from left to right, its circuit meets contactor K1 for drawing triple line from three-phase power line, meets the contactor K2 of parallelly connected K1 again; Pass current transformer again and intelligent microprocessor controller joins; Intelligent microprocessor controller and motor join, and between current transformer triple line exit and the outlet of intelligent microprocessor controller, are parallel with bypass contactor K3, on intelligent microprocessor controller import triple line, the semiconductor protector are installed.

The shortcoming of this control cubicle is a complex structure, and assembling is complicated, and when damage parts again, can not in time change, and adopts button control to be easy to generate problems such as repetitive operation in addition.

The utility model content

To above-mentioned defective, the purpose of the utility model provides a kind of intelligent motor starting box, and the easy repeated priming, the volume that exist with the starting box that solves prior art are bigger, complex structure, not easy-to-assemble technical problem.

For realizing above-mentioned purpose, the utility model has adopted following technical scheme:

A kind of intelligent motor starting box; It comprises a cabinet; Be provided with in the said cabinet between power switching module, end of incoming cables and the leading-out terminal and be provided with controllable silicon; Bypass contactor of each cross-over connection of each controllable silicon two ends is provided with the LED control panel that a Chinese character shows in the front of said cabinet, said LED control panel is connected with the inner power switching module of said cabinet through the driver circuit plate.

According to the described intelligent motor starting box of the utility model preferred embodiment, said bottom of cabinet bulk is provided with two binding posts that indicate input and output respectively, is connected respectively to said end of incoming cables and said leading-out terminal.

According to the described intelligent motor starting box of the utility model preferred embodiment, said power switching module is a plug formula module.

Owing to adopted above technical characterictic, make the utility model than prior art, have following advantage and good effect:

At first, the intelligent motor starting box that the utility model provides, but adopt the design of modular plug, when needing to change parts, only need simple plug to realize, safeguard like this and install all convenient.

Secondly, the intelligent motor starting box that the utility model provides adopts LED or LCD Chinese to show, not only operates intuitive and convenient, and can place the repeated priming problem that occurs easily in the pushbutton enable.

Certainly, implement any one specific embodiment of the utility model content, might not reach above whole technique effect simultaneously.

Description of drawings

Fig. 1 is the external structure sketch map of the said intelligent electric motor starting case of the utility model;

Fig. 2 is the primary system figure of the said intelligent electric motor starting case of the utility model;

Fig. 3 is the front view cut-away view of the said intelligent electric motor starting case of the utility model.

Embodiment

For ease of understanding,,, do being described in further detail to the preferred embodiment of the utility model below in conjunction with accompanying drawing.

As shown in Figure 1, the utility model provides a kind of intelligent motor starting box, and it comprises a cabinet 100, is provided with power switching module in the said cabinet 100, and these modules adopt plug formula structure, when safeguarding, only need change corresponding plug-in unit and get final product.

As shown in Figures 2 and 3, be provided with controllable silicon 103 between end of incoming cables 101 and the leading-out terminal 102, bypass contactor 104 of each each cross-over connection of controllable silicon 103 two ends is provided with between controllable silicon 103 and end of incoming cables 101 and moulds shell capacitor 105.

Be provided with the LED control panel 110 that a Chinese character shows in the front of said cabinet 100; Said LED control panel 110 is connected with the inner power switching module of said cabinet through the driver circuit plate; The action of 110 pairs of inside of LED control panel of can be directly showing through the man of operator is controlled like this; State shows at the display screen of LED control panel, just can prevent the problem of repeated priming, and each module corresponding work state also can access demonstration intuitively.

For ease of operation, be provided with two binding posts that indicate input and output respectively in said cabinet 100 bottoms, be connected respectively to said end of incoming cables 101 and said leading-out terminal 102.

More than disclosed only be the preferred embodiment of the utility model; But be not to be used for limiting itself, anyly have the knack of those skilled in the art, under the situation of the utility model spiritual connotation; The equalization of being done changes and changes, and all should drop in the protection range of the utility model.
