QT-18L

QT-18L is an accessory designed for electrical equipment and is widely used in many industrial applications. It is used to provide an electrical signal for low-current, high-voltage applications and is especially suitable for applications involving power transmission and distribution. The QT-18L accessories can help reduce the time and cost associated with installation and maintenance of electrical equipment.

The QT-18L accessories consist of a series of components, including a thermocouple, a thermocouple adapter, a temperature sensor, a current transformers, a relay distribution box, a relay, an indicator lamp, a manual switch and a resistor. The thermocouple consists of two wires of different metals connected to each other, one of which is made of copper and the other of iron. When the temperature of the connection point exceeds a certain value, the two metals make contact and a current is generated. This current is then transmitted to the adapters, which convert it to a specific voltage or current for the temperature sensor to measure.

The current transformers are used to measure alternating current. They are connected to the relay distribution box, which converts the current to a relay which in turn opens and closes its contacts in order to control a load. The indicator lamps provide a visual indication and can also be used as a warning signal for an overcurrent. The manual switches are used to manually control the relay and the resistor is used to reduce voltage and current.

The QT-18L accessories are relatively easy to install and use. They are designed to be durable, reliable and efficient, and provide users with a cost-effective way to control and monitor electrical applications. The QT-18L accessories are widely used in industrial applications, such as power generation, transportation, manufacturing, security systems, and medical equipment.

In summary, the QT-18L accessories are a great choice for a multitude of electrical applications, and can help reduce time and cost associated with installation and maintenance. They provide a reliable and efficient way to control and monitor electrical applications, and are an excellent choice for industrial applications.
