Abstract
An electric heating belt for an oil field gathering and transmission pipeline comprises a transformer (4), a rectifier (5), a triode (9), an electric contact thermometer (10) and the like, and is characterized in that one end of a power supply (1) connected with an electric heating belt (3) is connected with a normally closed contact (2) integrated with a relay (7) in series. The utility model is used for in the open-air gathering pipeline heat preservation in oil field, accessible automatic control component rational control electric heating area operating time, therefore can save the life of electric energy, extension electric heating area.
Description
Technical field: the utility model relates to a kind of compact electric apparatus product, especially for a kind of oil gathering and transportation pipelines heat tape of oil field gathering and transportation insulation.
Background technique: before the utility model, the heat tape that each oil field is used for the insulation of open-air gathering line mostly is does not have control function automatically, thereby long-term work not only causes waste of energy, has shortened the working life of heat tape yet.
Summary of the invention: the purpose of this utility model is: for the open-air gathering line insulation in oil field provides a kind of oil gathering and transportation pipelines heat tape, because increasing, this device have electric contact temp to take into account Automatic Control Components such as relay, thereby can rationally control operating time of heat tape, not only save electric energy, also prolonged the working life of heat tape.
The purpose of this utility model realizes by following measure: a kind of oil gathering and transportation pipelines heat tape, be by power supply, normally-closed contact, the ribbon heater, transformer, rectifier, electric capacity, relay, resistance, triode, electric contact thermometer constitutes, and power supply is connected with the transformer input end, the transformer output terminal connects the input end of rectifier, behind the output terminal cross-over connection electric capacity of rectifier, its anodal emitter that connects triode, its negative pole connects the collector electrode of triode by relay, an end that also connects electric contact thermometer simultaneously by resistance, the other end of electric contact thermometer is connected with the base stage of triode, and it is the normally-closed contact of one that a wherein end that it is characterized in that connecting the power supply of ribbon heater has been connected in series with relay.
The utility model is used for the open-air gathering line insulation in oil field, can rationally control the heat tape operating time by Automatic Control Component, thereby can save the working life of electric energy, prolongation heat tape.
Description of drawings: Fig. 1 is the structural representation of oil gathering and transportation pipelines heat tape.
Embodiment: oil gathering and transportation pipelines heat tape, its power supply 1 is connected with transformer 4 input ends, transformer 4 output terminals connect the input end of rectifier 5, behind the output terminal cross-over connection electric capacity 6 of rectifier 5, its anodal emitter that connects triode 9, its negative pole connects the collector electrode of triodes 9, also connects an end of electric contact thermometers 10 by resistance 8 simultaneously by relay 7, the other end of electric contact thermometer 10 is connected with the base stage of triode 9, and a wherein end that connects the power supply 1 of ribbon heater 3 has been connected in series with relay 7 and is the normally-closed contact 2 of one.
The working principle and the using method of oil gathering and transportation pipelines heat tape are: earlier ribbon heater 3 and electric contact thermometer 10 are placed on the gathering line to be incubated before using, connect power supply 1 again and just can carry out heat insulation work; Because being on-state, electric contact thermometer 10, normally-closed contact 2 is turnoff state in the work, power supply 1 will be connected the 3 pairs of gathering lines in ribbon heater and heat, after temperature reaches predetermined value, electric contact thermometer 10 is connected, give triode 9 base currents and make its conducting, this moment, the electric current of rectifier 5 anodal outputs then was back to rectifier 5 negative poles by triode 9 emitters, collector electrode through relay 7, relay 7 actions cause with it opens circuit for the normally-closed contact 2 of one, thereby cut-out connection ribbon heater 3 is connected with power supply 1, and ribbon heater 3 quits work; Otherwise after temperature fell back to below the predetermined value, electric contact thermometer 10 opened circuit, give the disappearance of triode 9 base currents and it is ended, and then cause relay 7 actions to make and its normally-closed contact 2 connections for one, and connection ribbon heater 3 is connected with power supply 1, and ribbon heater 3 works on.
Claims (1)
1. oil gathering and transportation pipelines heat tape, be by power supply, normally-closed contact, the ribbon heater, transformer, rectifier, electric capacity, relay, resistance, triode, electric contact thermometer constitutes, and power supply is connected with the transformer input end, the transformer output terminal connects the input end of rectifier, behind the output terminal cross-over connection electric capacity of rectifier, its anodal emitter that connects triode, its negative pole connects the collector electrode of triode by relay, an end that also connects electric contact thermometer simultaneously by resistance, the other end of electric contact thermometer is connected with the base stage of triode, it is characterized in that: it is the normally-closed contact of one that a wherein end of the power supply of connection ribbon heater has been connected in series with relay.
