In substations, switchgear stations and distribution rooms of industrial and mining enterprises, local overheating is highly likely to occur at parts such as switchgear contacts and cable joints due to oxidation, loosening or overload. Under the traditional mode, operation and maintenance personnel rely on infrared thermometers for regular inspections, but they cannot capture sudden temperature rises during the intervals between inspections, and are also limited by line of sight and distance, making it difficult to detect the real temperature inside the closed cabinets.
The core value of HIZ-SD-CW power grid temperature monitoring and early warning system from HizTech lies in upgrading the "periodic check-up" to "24/7 monitoring".
The power grid temperature monitoring and early warning system uses miniature wireless temperature sensors that can be directly attached or adhered to critical parts such as cable joints and busbars. The sensors are powered by batteries or inductive power supply, completely eliminating the need for the cumbersome signal line installation required by traditional temperature measurement methods. For the renovation of existing old stations, there is no need to drill holes in the switchgear, greatly protecting the sealing and insulation of the equipment.
The on-site sensors and wireless transmission devices of the system together form an on-site collection network. One wireless temperature monitoring host can be configured to receive up to 120 wireless temperature sensors, easily covering the entire distribution room. The host has a strong connection capability, supporting multiple communication methods such as RS-485, optical fiber, and Ethernet, and can be seamlessly integrated into the existing integrated automation system or main station platform.
The power grid temperature monitoring and early warning system can directly display the real-time temperature of each measurement point on the host display screen on-site. With the addition of an IoT module, the data can be uploaded to the IoT platform, enabling cross-regional and group-level unified monitoring.
The power grid temperature monitoring and early warning system is widely applicable to:
Substations/distribution stations: Monitoring of switchgear contacts and cable connection points.
Data centers: Temperature monitoring of UPS input/output cabinets and row head cabinets.
Railway transportation: Temperature measurement of key nodes in traction substations and catenary systems.
