Product Details
Function:
The ARTM100 electrical contact wireless temperature measurement system is suitable for temperature monitoring of high-voltage switchgear contacts and contacts, knife switch switches, high-voltage cable intermediate heads, dry transformers, low-voltage high current equipment, etc. The device is designed using ultra-low power consumption technology and consists of an embedded integrated touch screen, wireless temperature measurement transceiver, and wireless temperature sensor. The wireless temperature sensor exchanges information with the host through wireless signal transmission, which does not affect the insulation performance of the system and is safer to use. The device has the characteristics of complete isolation, convenient installation, strong anti-interference ability, and reliable operation, solving the safety problem of contact temperature monitoring under high voltage conditions.
Temperature measuring components
1 Temperature sensor
a. Wireless temperature sensor: A sensor installed at the contact point to be measured, which collects temperature and transmits it wirelessly.
Currently, there are three types of wireless temperature sensors:
ATE100
Internal battery powered
Communication distance 10M
Bolt fixed installation
ATE200
Internal battery powered
Communication distance 10M
Bundled installation
ATE300
CT power supply method
Communication distance 200M
Bundled installation
b. Wired temperature sensor: A sensor installed at the contact point to be measured, which collects temperature and transmits it through wired means. At present, the main wired temperature sensors are PT100:
2 receiving/display unit
a. Wireless temperature measurement transceiver equipped with one RS485 interface:
Online temperature measurement system configuration
1. Low voltage electrical contact wire temperature measurement/transformer winding temperature measurement
Note: Most ARTM8 temperature patrol detectors can be equipped with eight PT100 sensors, which are wired. When measuring low-voltage electrical contacts, the sensor PT100 needs to be insulated.
2. Wireless temperature measurement of electrical contacts in high and low voltage cabinets (single cabinet local display)
Description: ARTM-Pn wireless temperature measurement devices can be connected to 18 wireless temperature sensors, and the passive (CT power) method is ATE300 (bundled installation), The active (battery powered) methods are ATE100 (bolt type installation, mainly used for screw fixed lap points such as cables/copper bars) and ATE200 (strap type, mainly used for binding installation of circuit breaker contacts and other contacts, as installation is more convenient than ATE100, and lap points such as cables/copper bars are also commonly used).
3. Wireless temperature measurement and operation display function of electrical contacts in high and low voltage cabinets (local display)
Description: The ASD300/320 intelligent control device can be connected to 12 wireless temperature sensors, and the passive (CT power) method is ATE300 (bundled installation), The active (battery powered) methods are ATE100 (bolt type installation, mainly used for screw fixed lap points such as cables/copper bars) and ATE200 (strap type, mainly used for binding installation of circuit breaker contacts and other contacts, as installation is more convenient than ATE100, and lap points such as cables/copper bars are also commonly used).
4. Wireless temperature measurement of electrical contacts in high and low voltage cabinets (no need for local display)
Description: ATC200 wireless temperature transceivers can be connected to 12 active wireless temperature sensors, including ATE100 (bolt type installation, mainly used for screw fixed lap points such as cables/copper bars) and ATE200 (strap type, mainly used for binding installation of circuit breaker contacts and other contacts, as installation is more convenient than ATE100, and lap points such as cables/copper bars are also commonly used)* To receive temperature signals from active wireless temperature sensors in the same switchgear, if the number of wireless temperature sensors in the cabinet exceeds 12, multiple transceivers need to be configured
5 centralized (ATC400)
Description: The ATC400 wireless temperature transceiver can be connected to 240 passive wireless temperature sensors ATE300 (bundled installation), and can receive temperature signals from multiple wireless temperature sensors in the cabinet.
Wireless temperature measurement of electrical contacts in 6 high and low voltage cabinets (centralized local display)
a) Touch screen with ATC200
Description: The touch screen is connected to multiple ATC200 through RS485 bus to achieve centralized display of switch cabinet temperature. Each touch screen can be connected to an additional 20 ATC200, and each ATC200 can be connected to an additional 12 source wireless temperature sensors.
b) Touch screen with ATC400
Description: The touch screen is connected to an ATC400 through an RS485 interface to achieve centralized display of switchgear temperature. Each ATC200 can receive over 240 wireless temperature sensors.

Product installation
1. Installation method of touch screen
The touch screen used in the ARTM100 wireless temperature measurement system adopts panel embedded installation, and the product size and installation hole size are shown in Figure 1.1. The installation method is shown in Figure 1.2.
2. Installation of wireless temperature transceiver
The wireless temperature measurement transceiver can be installed using a guide rail (DIN35mm) or fixed with bolts, as shown in Figure 1.3.
3. Installation of wireless temperature sensors
There are two methods for wireless temperature sensors: strap fixation and bolt fixation. The strap type is suitable for the installation of handcart moving contacts; The bolt type is suitable for the installation of electrical overlap points fixed with bolts, such as the overlap of busbar, cable and busbar, and the overlap of isolation switch.
