What equipment in the substation needs temperature measurement

iVakarau ni ivakarau ni ivakarau ni transformer

The main types of faults in transformers include faults caused by transformer temperature rise and electrical faults. Ena kedra maliwa, transformer temperature rise faults account for a large proportion of the total faults, while transformer discharge faults account for a small proportion. Ena kedra maliwa, the service life of oil immersed transformers is mainly related to the service time of insulation materials. The decisive factor for the service life of insulation materials is the temperature of the insulation layer. O koya gona, the temperature of oil immersed transformers determines the service life of transformers.

FJINNO independently developed switch cabinet point type fiber optic online temperature measurement system, fluorescence fiber optic temperature sensor online monitoring temperature device, real-time online temperature monitoring of the operating temperature of electrical equipment, especially the switch cabinet contacts, busbars, electrical contacts and other easily heated positions.

Reactor temperature measurement

Reactors are the main auxiliary equipment of long-distance transmission systems, playing an important role in power transmission due to their superior electrical performance. During the operation of a reactor, it is often due to external factors, internal structure, and other factors that the reactor may experience local temperature rise and overheating, ultimately leading to local burnout or even scrapping.

Temperature measurement of lightning arrester

Temperature detection is an old-fashioned detection method and an important supplement to lightning arrester detection. Although the temperature cannot reflect the quality of the lightning arrester, it can be seen from the data whether the lightning arrester is working. When tested under system voltage, the temperature of the lightning arrester is related to its energy loss, but not directly related to environmental interference and harmonic content of the system voltage.

Capacitor temperature measurement

Capacitors often encounter various faults during operation, which pose a significant threat to the safe and normal operation of the power system. The common faults of capacitors in power operation include oil leakage, poor insulation, and burnt fuses. Ena kedra maliwa, the most harmful and frequently occurring faults are capacitor faults caused by heating.

Circuit breaker temperature measurement

The circuit breakers in the switchgear are commonly used during operation, which can easily lead to wear on the dynamic and static contacts of the circuit breakers, loose fasteners on the terminal busbar, and other phenomena; If the circuit breaker is not subjected to temperature monitoring, it is possible to generate high temperature heat, which can cause aging of the insulation components of the switchgear and potentially lead to fire or damage to power equipment.

The above is just an example of several commonly used equipment in substations that require temperature measurement. Fluorescent fiber optic temperature measurement systems can be used in substations.

What are the types of temperature measurement methods used in substations

Ena gauna oqo, infrared testing is being conducted. When substation operation and maintenance personnel collect the temperature of outdoor isolation switches, circuit breakers, transformers and other substation equipment in the substation, they mainly use manual operation. That is, the operator needs to go to the site and use a handheld infrared imaging instrument to measure the temperature and record the connection of the knife switch mechanism, knife switch head, and knife switch sheath. The current outdoor knife switch temperature measurement work is mainly carried out by substation operation and maintenance personnel on site, using handheld infrared imaging devices to measure the temperature of the knife switch mechanism, knife switch head, and knife switch sheath connection. After returning to the office, data is manually recorded and recorded. A large amount of data analysis is conducted on the three phases of a set of knife switches based on time points every day, which is a huge workload, and personnel classification and organization lack specificity.

The drawbacks of infrared temperature measurement methods

The existing infrared temperature measurement mode occupies a lot of time and energy for operation and maintenance personnel, resulting in a relative shortage of personnel, time conflicts, and scattered energy in power grid accident handling, switching operations, and other temporary work. It is extremely easy to cause inadequate equipment inspection or lack of focus on switching operations, reducing production efficiency and work quality, and bringing potential safety hazards to the safe operation of the power grid.

The lack of targeted temperature measurement increases the operational risk of substations.
The existing substation temperature measurement adopts a unified inspection mode for isolation switches of the same voltage level. The determined inspection cycle includes all inspection items of the substation in each inspection. This repeated and evenly applied search method often causes psychological fatigue for operation and maintenance personnel during inspections, making it difficult to detect equipment problems.

Operation and maintenance are not synchronized, resulting in wasted resources for repeated entry into the station.
The maintenance plan of the substation is disconnected from the inspection and temperature measurement plan of the substation, and the time for entry operation and entry temperature measurement is often inconsistent, causing operation and maintenance personnel to repeatedly enter the station, wasting a lot of time on the way to and from the substation. The opportunity to enter the station is not fully utilized, the workload increases, and the temperature measurement efficiency decreases.

Disadvantages of wireless temperature measurement in substations

Wireless temperature measurement method, due to the connection between high-voltage switch contacts and busbar bars in high voltage, high temperature, high magnetic field, and extremely strong electromagnetic interference environments, currently commonly used thermal resistance and thermocouple temperature sensors are made of metal materials and require metal wires to transmit signals. Only wireless communication can be used for high and low voltage isolation; Electronic sensors require batteries or small current transformers to provide power to the temperature measurement chip, and then transmit the signal obtained by the temperature measurement chip wirelessly to the receiver through the wireless chip. Although this solution achieves wireless transmission of temperature signals, the battery needs to be replaced regularly for power supply, and the battery has poor high-temperature resistance, which affects the operation of the power department
