Abstract
The utility model relates to a plastic insulation box for protecting a measurement and control circuit of an electric furnace transformer, which comprises a rectangular plastic insulation box body. An insulation panel is arranged on the front side of the plastic insulation box body, mounting boards are fixedly connected to the upper lateral side and the lower lateral side of the insulation panel respectively through bolts, a terminal board is fixed on the back side of the plastic insulation box body. According to the plastic insulation box for protecting the measurement and control circuit of the electric furnace transformer, a rear-plugging structure is adopted, lockable joints are adopted for plugins, therefore poor plugging is avoided, operation and maintenance are facilitated simultaneously, renewal time is short, and power cut time due to faults is reduced. Liquid crystal display (LCD) on the insulation panel of the box structure can be used for displaying information which is clear at a glance. The plastic insulation box is simple and practical.
Description
Technical field
The utility model belongs to electric furnace resist technology field, especially a kind of plastic insulation casing that is used for furnace transformer protection telemetry circuit.
Background technology
Furnace transformer protective device function singleness of the prior art can not satisfy on-the-spot needs.In the electric furnace suitability for industrialized production, the furnace transformer condition of work is abominable, and the pressure regulation grade is many, and secondary voltage is low, and electric current is up to amperes up to ten thousand, because the specific (special) requirements of smelting process technology, electric furnace must bear big rush of current and voltage impulsion.The electric furnace protective device of smelting industry use at present; Exist antijamming capability low mostly; Automatic protection functions and observing and controlling function are few, and reaction sensitivity is lower, and the observing and controlling function is few; Can not be to non electrical quantities such as transformer, reactor, loaded switch, oil-water cooler protections, defective such as the information transmission channels is few.
The utility model content
The purpose of the utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of plastic insulation casing that is used for furnace transformer protection telemetry circuit is provided, and this body structure is simple, not only can realize the protection and the light weight of furnace transformer, and is easy to use.
The purpose of the utility model solves through following technical scheme:
This plastic insulation casing that is used for furnace transformer protection telemetry circuit; The plastic insulation casing that comprises rectangle; The front side of said plastic insulation casing is provided with insulating panel; The side up and down of said insulating panel is fixedly connected with mounting panel respectively through screw, and the rear side of said plastic insulation casing is fixed with a terminal board.Be provided with shockproof pad between said mounting panel and the insulating panel.
Above-mentioned insulating panel is provided with LCDs, first button area, second button area and the 3rd button area; Said second button area and the 3rd button area are divided into the both sides of LCDs; Said first button area is arranged at the below of LCDs.
The side of above-mentioned plastic insulation casing offers louvre or heat radiation slit.
The utlity model has following beneficial effect:
The plastic insulation casing that the utility model is used for furnace transformer protection telemetry circuit can adopt back plug-in structure; Being about to each plug-in unit is arranged on the terminal board; But each plug-in unit can adopt latching connector, can avoid patching bad, makes things convenient for operation maintenance simultaneously; The replacing time is short, shortens the fault outage time; And this shell structure is in light weight, and is firm in structure, good heat dissipation, and the life-span is long.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is insulating panel 2 structural representations of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
This kind is used for the plastic insulation casing of furnace transformer protection telemetry circuit; The plastic insulation casing 1 that comprises rectangle; The front side of this plastic insulation casing 1 is provided with insulating panel 2; The side up and down of insulating panel 2 is fixedly connected with mounting panel 4 respectively through screw, and the rear side of plastic insulation casing 1 is fixed with a terminal board 3.Be provided with shockproof pad between mounting panel 4 and the insulating panel 2.In order to strengthen heat radiation, offer louvre or heat radiation slit in the side of plastic insulation casing 1.
Insulating panel 2 is provided with LCDs 6, first button area 7, second button area 8 and the 3rd button area 9; Second button area 8 and the 3rd button area 9 are divided into the both sides of LCDs 6; Said first button area 7 is arranged at the below of LCDs 6.
In the most preferred embodiment of the utility model, but each plug-in unit on the terminal board 3 adopts latching connector, has avoided patching bad, makes things convenient for operation maintenance simultaneously, and the replacing time is short, shortens the fault outage time.
As shown in the figure, said insulating panel 2 is greater than plastic insulation casing 1 anterior end surface, so that whole shell structure can cooperate installation with the associated electrical cabinet; Said terminal board 3 is less than the end plate of said plastic insulation casing 1.
