The working principle of dry-type transformer thermostats The dry-type transformer temperature controller is a new generation of controller designed for the safe operation of dry-type transformers. The controller adopts single-chip microcomputer technology, and uses three platinum thermal resistors embedded in the three-phase winding of the dry-type transformer to detect and display the transformer.

First, the use of electronic temperature controller The electronic temperature controller (resistive type) is measured by the method of resistance temperature sensing, and generally uses platinum wire, copper wire, tungsten wire and semiconductor (thermistor, etc.) as the temperature measurement resistor, and these resistors have their own advantages and points. Home Air Conditioner ...

1. Welding and installation of the lower support of the guide wire: determine the position at the bottom of the container according to the requirements of the movement direction of the float of the level gauge, and weld or rivet the lower support of the fixed guide wire. If the equipment does not have welding conditions, the heavy anchor fixing method can be used to fix the guide wire under the support. For example, the liquid level wave in the container ...

1. Support welding under the guidewire: According to the direction of the movement of the buoy of the level gauge, determine the position at the bottom of the container, and fix the guide bracket (piece 1) under the welded or riveted steel wire 2. Install the guide rail joint. (1) Straighten the wire forcefully and fix it at the lower support, taking care not to ...

Mechanical thermostat mainly refers to a temperature control method that adjusts refrigeration by rotating the button, with an expanding thermostat, which will automatically expand and contract according to the change of temperature, so as to control the power supply, the most primitive type, and the structure is relatively simple. Advantages of mechanical thermostats: ...

Thermostat, according to the temperature change of the working environment, physical deformation occurs inside the switch, so as to produce some special effects, a series of automatic control elements that produce on-on or off-action actions, or different principles of electronic components at different temperatures and working states to give ...

The float level gauge is widely used, mainly used in petroleum processing, food processing, chemical industry, water treatment, manufacturing, electric power, papermaking, metallurgy, ships and boilers and other industrial automation processes to measure and control the level. 1. Pay attention to the specific working conditions. As introduced ...

The selection of thermocouples should be based on comprehensive considerations such as the operating temperature range, the required accuracy, the operating atmosphere, the performance of the measured object, the response time and the economic benefits. 1. Selection of measurement accuracy and temperature measurement range 1) The operating temperature is 1300-1800°C, and the accuracy is required to be more accurate than ...

Fault 1: The thermostat does not turn on (the screen does not display) Analyze the causes 1. Wrong wiring; 2. The voltage of the input terminal is not enough or the input terminal is damaged by the empty leakage guarantee; 3. Whether the cable between the panel and the power board is broken or plugged incorrectly; 4. Load short circuit or broken ...
