Description
Technical field
The utility model discussion be the electrical control gear of resistance-type heating boiler, belong to control class automatically.
Background technology
Along with the raising of people to environmental protection consciousness, industry and the used boiler of life from the coal-burning boiler to the oil burning boiler, gas fired-boiler develops into the electrically heated boiler of present no any disposal of pollutants.Yet use this electrically heated boiler " electricity price " to become " bottleneck " that restriction electric boiler large tracts of land is promoted, still, when electricity price is carried out " peak ", " paddy " different price, make that being applied to of electrically heated boiler may.Because the electricity price of low ebb is material benefit relatively, but the low ebb electricity generally all at night after the 11:00 to the morning next day 6:00, and the custom of China's people's lives make work at night tired out easily, and powerful electric equipment is once mishap to some extent, the loss of the person or property is caused in the capital, because electrically heated boiler is still in the popularization stage, so it is supporting with it still not have complete typing electrical control equipment at present.
Summary of the invention
The technical solution of the utility model is to adopt the control method of PLC+ touch-screen, and a kind of electrical control gear of full-automatic, safe and reliable resistance-type heating boiler is provided for people.
The utility model is made up of one-shot measurement element, central processing unit, touch-screen, main control loop.The one-shot measurement element has boiler overheat, superpressure, under-voltage and pressure of return water is low, earth leakage protective, circulating pump output contact, leaving water temperature, return water temperature, outdoor temperature and backup circuit breaker.The signal that they send connects central processing unit, and the output signal of central processing unit connects the ac contactor coil in each main control loop respectively.In addition, also have special purpose interface to send touch-screen to show from central processing unit, simultaneously, touch-screen instructs output by interface to central processing unit, and above control procedure is finished under the programmable software cooperation.Main control loop is according to the optional many groups of boiler capacity size, and every group of main control loop all has voltage and the indication of every electric current, and it connects three-phase alternating-current supply by tentaculum, the air switch of electric heating tube, earth leakage protective device, interchange after connecting.
The design of this device meets Ministry of Machine and Electronics Industry's boiler and detects and supporting detailed rules and regulations requirement, makes according to the professional standard GB7251-1997 of the People's Republic of China (PRC).Have reliability height, automaticity height, easy to use, simple to operate, feature richness, control advantage flexibly.

Fig. 2 is the utility model main control loop circuit diagram;
The specific embodiment
Is example with the utility model electrical control gear with 6 groups of main control loops, and central processing unit is selected for use: 6ES7; Touch-screen is selected 6AV3627 for use; Air switch is selected for use: CMI series; Interchange is selected for use by tentaculum: 3TF series; Earth leakage protective device is selected for use: LJ series; Sending signal from the scene connects respectively: the leaving water temperature signal is pressed A+, the A-of 6ES7; The return water temperature signal meets B+, the B-of 6ES7; The outdoor temperature signal meets C+, the C-of 6ES7; The overtemperature signal of boiler meets the I0.0 of 6ES7; Boiler superpressure signal meets the I0.1 of 6ES7, and boiler is owed the I0..2 that signal meets 6ES7, and the pressure of return water low signal meets the I0.3 of 6ES7; The earth leakage protective signal meets the I0.4 of 6ES7, and the circulating pump output signal meets the I0.5 of 6ES7, and backup circuit breaker meets the I0.6 of 6ES7.The output Q0.0 of 6ES7 connects ac contactor coil in the first via main control loop; The output Q0.1 of 6ES7 connects ac contactor coil in the second road main control loop; The output Q0.3 of 6ES7 connects ac contactor coil in the Third Road main control loop; The output Q0.4 of 6ES7 connects ac contactor coil in the four road main control loop; The output Q0.4 of 6ES7 connects ac contactor coil in the five road main control loop; The output Q0.5 of 6ES7 connects ac contactor coil in the six road main control loop; The output Q0.6 device taking alarm of 6ES7.6ES7 also is connected with 6AV3627 with special purpose interface; L1 and n connect power supply.A-is connected with B+, B-and C+ edge joint.Main control loop connects: three phase mains connects voltmeter, three phase mains through change-over switch, and each connects ammeter through current transformer, and three phase mains connects electric heating tube after connecing CMI series air switch, 3TF Series AC Contactor, LJ series earth leakage protective device.
This electrical control gear is controlled with programmable software, can finish following protective effect:
1, circulating pump interlock protection: necessary first start-up system circulating pump before the operation boiler control system, otherwise control system can't be moved.
2, overtemperature prote: after steam generator system operation, when boiler temperature surpasses the maximum temperature that the user sets, control system will be sent sound and light alarm sound and stop the operation of boiler automatically.
3, overpressure protection: when boiler during in running status, when the pressure of boiler had surpassed the pressure setting range, control system was sent sound and light alarm and is stopped the operation of boiler automatically.
4, under-voltage protection: when steam generator system pressure was lower than boiler low pressure setting range, control system was sent sound and light alarm and blowing out automatically.
5, earth leakage protective: when electric leakage appearred in the boiler electric heating tube, control system was sent sound and light alarm and is stopped the operation of steam generator system automatically.
6, pressure of return water is low excessively: when boiler in when operation, the pressure of return water of system is low excessively, control system is sent sound and light alarm.
7, standby gauge tap: control system is provided with standby start stop switch, when the control touch-screen breaks down or during other problem, as long as backup circuit breaker is put to opening state, system gets final product work, when the maintenance personal does not also arrive in, is unlikely to influence and produces like this.
