电力调整器的两种负载介绍 铂电阻温度传感器 维连电子


The power adjustor is a widely used power adjustment device, which is also a energy -saving and environmentally friendly product. And it is applied to equipment in various industries, such as electric heating high -temperature boilers, glass reinforced furnaces, high -temperature ceramic kiln, metal thermal treatment equipment, fiber dyeing heating equipment, physical instruments, chemical instruments, power voltage conveying equipment, transformers, transformers There are many industries such as one -sided control and so on. Below, let me briefly introduce the two load conditions of the power adjustment device.

1. Sensory load:
The controller can run with a transformer, and uses the power -to -electricity to slowly start the magnetic field and gradually decreases the magnetic field; the pulse wide variable trigger technology can provide a lock time for the crystal tube engine to avoid unreliable narrow pulse triggers. High -reliability single -chip microcomputer hardware system and proprietary software design solution make this machine have no current impact and can work stable for a long time under various industrial complex power grid environments. It can be widely used in industrial low voltage and large current electric heating equipment, such as metallurgical, building materials chemical, light spinning and other industries. Various occasions that need to be connected in series in the chemical industry reactor.
2. Blind load:
1) Smaller of thermal inertia: Use the power -on and slow starting for 1 minute or longer, avoid the impact current near 700 ° C. Gradually fascinating the magnetic field and gradually decaying the magnetic field; the pulse width variable trigger technology can provide enough lock time to reach the crystal tubular engine station, avoiding the non -reliable trigger of narrow pulses. (Including resistance furnaces, heater, oven, baked lane, infrared radiation heating lamps, etc.), etc.) Automatic/manual control (heating, constant temperature, automatic temperature control) and application of pressure regulation, lighting, and cross -current motor adjustment Speed, plating, battery charging and other equipment, especially for electric heating systems with less heat inertia.
2) Larger categories of thermal inertia: Silicon molybdenum, molybdenum wire, tungsten, platinum, and white gold cold and hot resistance have changed greatly, but the resistance and temperature relationship is linear. Using antihypertensive transformers, XCT1 current limit, etc. Current limit. In addition, SR53 linear limits can be used, and the output power can automatically follow the setting value of the instrument.
3). Integrated technology of regulating pressure and regulation: The pressure regulation method has small load current impact and is suitable for transformer control, but it will inevitably bring power pollution and reduce power factor. The method of excessive zero -adjustment can not limit the current, and the cold -state shock will affect the life of the heating pipe. The pulse transformer output, automatically determine the phase of the phase, inhibit the cross -loop synchronous circuit with a high high interference capacity of the power supply, has three alarm tips: overcurrent., Overheating, and underwriting, and the rated current is 20 to 1500A. Intelligent AC power controllers can be widely used in voltage regulation in various fields of industries, constant voltage constant currents, constant power adjustment, suitable for resistance load, inductive load, transformers and motor soft control.
