Abstract
The utility model discloses an intelligent electric heater control cabinet, comprising a control cabinet body. The control cabinet body is provided with an intelligent digital display temperature controller, an AC contactor, breakers, and electric connectors. The outside of the control cabinet body is provided with a temperature sensor and electric heaters. The temperature sensor is connected with the control cabinet body through flexible wires, and transmits temperature signals. An end of the AC contactor is connected with the breakers, and the other end is connected with a power supply through the electric connectors. The breakers are connected with the electric heaters through the electric connectors. The intelligent digital display temperature controller cooperates with the temperature sensor. The intelligent digital display temperature controller controls the breakers and the AC contactor. Two ends of the electric heater are provided with connecting pieces. The intelligent electric heater control cabinet is advantaged by integrating temperature measurement circuit, a temperature control circuit, and a logic protection circuit, and the control cabinet can set and control required temperature of a lubricating device, and troubles of installing and constructing wiring, and meanwhile the control cabinet is beneficial for operation and maintenance.
Description
Technical field
The utility model relates to a kind of control box, relates in particular to a kind of Intelligent electric well heater control box.
Background technology
Existing electric power lubricating utensil with electric heater control box only for controlling the start and stop of electric heater; it is not with virtual protection circuit; be not with temperature survey and temperature to control; the open and close function of electric heater power supply is only provided; the temperature survey relating to is arranged on lubricating utensil body; the temperature that relates to control by control DCS realize; the temperature of lubricating utensil is controlled needs temperature measurement equipment, control box, middle control DCS jointly to complete; installation wiring is complicated; change design temperature needs the cooperation of DCS, and operation and maintenance is extremely inconvenient.
Therefore,, for addressing the above problem, spy provides a kind of new technical scheme.
Utility model content
The purpose of this utility model is to provide a kind of Intelligent electric well heater control box.
The technical solution adopted in the utility model is:
A kind of Intelligent electric well heater control box, comprise control box casing, in described control box casing, be provided with intelligent digital temperature controller, A.C. contactor, isolating switch and electric connector, described control box casing outside is provided with temperature sensor and electric heater, described temperature sensor is connected with control box casing by flexible cord, and transmit temperature signal, described A.C. contactor one end is connected with isolating switch, the other end is connected with power supply by electric connector, described isolating switch is connected with electric heater by electric connector, described intelligent digital temperature controller matches with temperature sensor, described intelligent digital temperature controller is controlled isolating switch and A.C. contactor, described electric heater two ends are provided with web member.
Described web member is air plug electric connector.
The utility model has the advantages that: integrated temperature survey, temperature are controlled and virtual protection circuit, can to lubricating utensil, require temperature set and control on the spot, reduced the trouble of installation wiring, simultaneously stronger and operation and maintenance.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is control principle drawing of the present utility model.
Fig. 2 is electrical schematic diagram of the present utility model.
Fig. 3 is electrical principle service chart of the present utility model.
Wherein: 1, control box casing, 2, intelligent digital temperature controller, 3, A.C. contactor, 4, isolating switch, 5, electric connector, 6, temperature sensor, 7, electric heater, 8, flexible cord, 9, air plug electric connector.
Embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, to of the present utility model, be described in further detail, this embodiment is only of the present utility model for explaining, does not form the restriction to protection domain of the present utility model.
As Figure 1-3, a kind of Intelligent electric well heater control box of the present utility model, comprise control box casing 1, in control box casing 1, be provided with intelligent digital temperature controller 2, A.C. contactor 3, isolating switch 4 and electric connector 5, control box casing 1 outside is provided with temperature sensor 6 and electric heater 7, temperature sensor 6 is connected with control box casing 1 by flexible cord 8, and transmit temperature signal, A.C. contactor 3 one end are connected with isolating switch 4, the other end is connected with power supply by electric connector 5, isolating switch 4 is connected with electric heater 7 by electric connector 5, intelligent digital temperature controller 2 matches with temperature sensor 6, intelligent digital temperature controller 2 is controlled isolating switch 4 and A.C. contactor 3, electric heater 7 two ends are provided with air plug electric connector 9.
The utility model has the advantages that: integrated temperature survey, temperature are controlled and virtual protection circuit, can to lubricating utensil, require temperature set and control on the spot, reduced the trouble of installation wiring, simultaneously stronger and operation and maintenance.
Control principle of the present utility model: before lubricating utensil work, need to be according to the operation requirement of lubricating utensil, the lower limit of setup control temperature, higher limit, when temperature is during lower than lower limit, the contactor ALM2 closure of often making war, well heater brings into operation, when higher than higher limit, the normally closed point of contactor ALM1 disconnects, well heater quits work, the variation repeatedly of oil temperature, contactor is also can be accordingly closed and open, thereby the break-make of control heater, lubricating utensil medium temperature is controlled in the scope of setting, this control box also receives the high temperature alarm signal from well heater, in firing equipment during excess Temperature, the signal of electric heater inside is made war closed, to DCS, send an alerting signal, DCS can take corresponding measure according to situation at that time.
