Abstract
The utility model relates to a self-controlled high-pressure oil-tank electric heater which is composed of a heating rod, a rod body supporting rack and an electrical control cabinet. The self-controlled high-pressure oil-tank electric heater is characterized in that a plurality of electric heating tubes are connected in series and in parallel in a combined type, and the self-controlled high-pressure oil-tank electric heater can be used in 1140KV high-pressure heating directly, and the usable range of the power of the electric heater is enlarged. Moreover, the electric heater is also added with automatic control and buzzing warning apparatus, etc., thus the labor intensity of an operator is reduced and the security is increased.
Description
A kind of autocontrol high pressure oil tank electric heater belongs to the electrical heated appliance field.
The mode of heating of oil is to adopt the coiled steam heater in traditional oil storage tank, because its rate of failure height, repair and maintenance difficulty and equipment investment thereof are bigger, and progressively replaced by electric heater, oil tank electric heater in recent years mainly contains two kinds of mode of heatings, a kind of is to be wrapped in the heating cable of excellent core body as heating element with inserting in the excellent shell, another kind of mode of heating is to insert electrothermal tube as heating element in excellent shell, these two kinds of Electric heating generally are to adopt common voltage, the mode of artificially controlling temperature, it is bigger to there is labor strength, and the restriction that is subjected to the electrically heated rod weight and volume, its heating power design scope of application smaller defect.
It is a kind of temperature automatically controlled that the purpose of this utility model is to provide, and is applicable to high voltage and can increases the autocontrol high pressure oil tank electric heater of its power designs scope of application under the prerequisite that does not increase the electrical bar volume.
The purpose of this utility model realizes as follows.
Autocontrol high pressure oil tank electric heater is by electrically heated rod, barred body bracing frame and electric cabinet are formed, it is characterized in that having in the said electrically heated rod quantity is the electrothermal tube of 3 integral multiple, electrothermal tube wherein is equally divided into three groups, earlier every group of electrothermal tube connected successively, then that three groups of electrothermal tubes are end to end successively, its contact connects with lead with three contacts of electrical control cubicles mesohigh vacuum contactor respectively, connect with external high-voltage power-line respectively with other three contacts of these three corresponding high-pressure vacuum contactors in contact, the automatic control equipment that electric heater is provided with is by the automatic control circuit in the electrical control cubicles and be positioned at the lip-deep thermocouple of electrically heated rod barred body with its point for measuring temperature that links with lead and form.
Automatic control circuit in the oil tank electric heater electrical control cubicles is by the 1140V/220V control transformer, and the temperature display controller in the 220V circuit, thermocouple, buzzer, indicator light are formed.
The point for measuring temperature of thermocouple is positioned on the electrically heated rod barred body surface of barred body bracing frame retainer ring one end in the automatic control equipment of oil tank electric heater, and the hole that the terminals of thermocouple pass on the barred body bracing frame mounting flange connects with the interior automatic control circuit of lead and electrical control cubicles.
Because the electrothermal tube in the utility model electrically heated rod has adopted series and parallel to mix the connecting mode of using, thereby under the prerequisite that does not increase the electrically heated rod volume, can increase the voltage endurance capability of electrical bar and use power, make voltage endurance capability can reach 1140 volts, use power also to be increased to 24KW by original 18KW, enlarged the scope of application of electric heater, set up the labour intensity that automatic temp controller can alleviate or reduce the operational administrative personnel effectively, install the fail safe that the buzzing warning device can increase electric heater additional.
Below in conjunction with accompanying drawing the utility model is described further.
Accompanying drawing 1 is the utility model overall structure schematic diagram.
Accompanying drawing 2 is the utility model electric appliance circuits schematic diagrams.
A kind of autocontrol high pressure oil tank electric heater, by electrically heated rod 1, barred body bracing frame 5 and electrical control cubicles 4 are formed, 1140 volts of external three-phase high-voltage line A, B, C connects with three contacts of high-pressure vacuum contactor CJ by high-tension fuse 1-3RD, with other three contacts of this three corresponding high-pressure vacuum contactor CJ in contact respectively with electrically heated rod in three lead-out wire a of electrothermal tube, b, c connects, be provided with R1-R9 totally nine electrothermal tubes in the electrically heated rod 1, these nine electrothermal tubes are equally divided into three groups and every group of electrothermal tube connected successively, be R1-R3, R4-R6, R7-R9 respectively is one group, and then these three groups of electrothermal tubes are end to end successively, obtain three node a, b, c.
Automatic control section in the electrical control cubicles is 1140 volts high-tension electricity to be become 220 volts common voltage by transformer BK, in 220 volts circuit, be provided with automatic temperature-controlled circuit, temperature automatically controlled circuit is by temperature display controller XM, thermocouple 3 and buzzer D and indicator light LD form, the thermometric end of thermocouple 3 is positioned on the electrically heated rod barred body surface of barred body bracing frame retainer ring 2 one ends, and the hole that the terminals of thermocouple 3 pass on the mounting flange 6 of barred body bracing frame 5 is connected with temperature display controller XM in the electrical control cubicles.
The operating process of present embodiment is as follows:
Closed K1, indicator light UD is bright.
ZK is transformed into when automatic, the control shelves of temperature display controller XM are allocated to desired location, it is design temperature, the control shelves are dialled and are got back to the measuring position then, and the automatic control system of electric heating is simultaneously started working each closing of contact of high-pressure vacuum contactor, the LD lamp is bright, temperature rises in the oil tank, and when temperature reached set point, control system was cut off the power supply automatically, each contact of high-pressure vacuum contactor disconnects, at this moment, the LD lamp goes out, and electric heater stops heating, sound a buzzer in the control cubicle, this moment, the staff must carefully check a jar interior oil storage situation, with operate as normal and the safety in production of guaranteeing electric heater, when temperature drops to minimum control temperature, the temperature display controller promptly sends signal to other elements, the LD lamp is bright, and electric heater restarts work, controls oil storage tank thus automatically and fluctuates in range of set temperature.
