Description

Technical Field

[0001] The present invention relates to the technical field of temperature measurement, and in particular to a non-contact intensive busbar joint temperature detection device and a temperature compensation method thereof. Background Art

[0002] The demand for temperature measurement at dense busbar connections is increasing. Contact probe temperature measurement is basically not recognized and adopted by customers due to safety risks (the temperature probe contacts the busbar, resulting in a decrease in the overall insulation performance of the busbar).

[0003] Non-contact (infrared) temperature measurement solutions have become widely available. Although they offer significantly improved safety and insulation compared to contact-based solutions, they still have certain limitations in temperature measurement accuracy. Foreign high-precision infrared temperature sensors, while offering superior compensation algorithms, are expensive. Domestically produced infrared temperature sensors, after extensive field testing by ABB / Schneider Busbar, have demonstrated an error of at least 2-5°C compared to contact-based solutions.

[0004] The reason is that the measurement accuracy of non-contact (infrared) probes is affected by the following aspects: 1. The different installation distances between the infrared probe and the busbar being measured cause errors; 2. The infrared probe is affected by changes in ambient temperature (such as the change of seasons), which causes errors; 3. The infrared probe is affected by ambient humidity, which causes errors.

[0005] Therefore, the present invention automatically compensates the temperature measurement accuracy of the infrared probe twice by combining hardware and software to achieve an actual temperature value that is basically consistent with that of contact temperature measurement.

[0058] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0059] like Figure 1 and Figure 2As shown, the embodiment provides a non-contact dense bus joint temperature detection device, which is installed at the bus duct joint. The device comprises a shell 1, a microprocessor unit 100, an ambient temperature sensor 101, an ambient humidity sensor 102, a two-bus communication circuit 103, a first infrared temperature sensor 104, a second infrared temperature sensor 105, a third infrared temperature sensor 106, and a distance measuring sensor 107 integrated in the shell 1. The probes of the ambient temperature sensor 101 and the ambient humidity sensor 102 are exposed to the shell 1. The probes of the first infrared temperature sensor 104, the second infrared temperature sensor 105, the third infrared temperature sensor 106, and the distance measuring sensor 107 are exposed to the shell 1 and are aligned above the bus L1, the bus L2, the bus L3, and the bus N in the bus 2 in sequence.

[0060] The ambient temperature sensor 101 is used to detect the ambient temperature value Te of the environment in real time.

[0061] The ambient humidity sensor 102 is used to detect the ambient humidity value HRe of the environment in real time.

[0065] The third infrared temperature sensor 106 is used to detect the temperature value T3p of the bus L3 in real time.

[0066] The microprocessor unit 100 is used to perform temperature value compensation ΔTh due to bus distance deviation. Since there are certain differences in the design of bus duct structures by dense bus manufacturers, the vertical distance between the joint shell surface and the bus is 3-10 cm, and the temperature compensation algorithm is as follows:

[0067] If the current vertical distance value Hc is less than or equal to 3 cm, then ΔTh=0.

[0068] If 3 cm < current vertical distance value Hc ≤ 6 cm, then ΔTh=-0.75+Hc / 4.

[0073] 5℃<current ambient temperature average value Tev≤30℃, then ΔTte=0;

[0074] 30°C < current ambient temperature average value Tev ≤ 55°C, then ΔTte = -2.75 + Tev / 25.

[0075] The microprocessor unit 100 is used to compensate the temperature value ΔThr caused by the difference in ambient humidity. When the infrared humidity sensor operates in a high humidity environment, the measurement accuracy has a certain deviation:

[0076] The average value HRev of the ambient humidity within the most recently set time period (eg, one minute) is calculated based on the ambient humidity value HRe received in real time.

[0077] If the current average ambient humidity HRev≤75%RH, then ΔThr=0;

[0078] 75%RH<current average humidity HRev≤95%RH, then ΔThr=1.05-HRev / 75.

[0079] The microprocessor unit 100 is used to upload the temperature value T1c corresponding to the busbar L1 after the current temperature compensation, the temperature value T2c corresponding to the busbar L2 after the current temperature compensation, and the temperature value T3c corresponding to the busbar L3 after the current temperature compensation to the two-bus system through the two-bus communication circuit 103:

[0080] T1c=T1p+ΔTh+ΔTte+ΔThr;

[0081] T2c=T2p+ΔTh+ΔTte+ΔThr;

[0087] 3cm<current vertical distance value Hc≤6cm, then ΔTh=-0.75+Hc / 4;

[0088] 6cm<current vertical distance value Hc≤10cm, then ΔTh=-0.55+Hc / 3.

[0089] S3. The microprocessor unit 100 performs temperature compensation ΔTte due to the difference in ambient temperature: based on the ambient temperature Te received in real time, the average ambient temperature Tev within the current set time period (one minute) is calculated;

[0090] The current average ambient temperature Tev≤5°C, then ΔTte=1.35-Tev / 25;

[0091] 5℃<current ambient temperature average value Tev≤30℃, then ΔTte=0;

[0092] 30°C < current ambient temperature average value Tev ≤ 55°C, then ΔTte = -2.75 + Tev / 25.

[0093] S4. The microprocessor unit 100 performs temperature compensation ΔThr due to the difference in ambient humidity: the average ambient humidity value HRev within the current set time period (one minute) is calculated based on the ambient humidity value HRe received in real time;

[0095] 75%RH<current average humidity HRev≤95%RH, then ΔThr=1.05-HRev / 75.

[0096] S5. The microprocessor unit 100 uploads the temperature value T1c corresponding to the busbar L1 after the current temperature compensation, the temperature value T2c corresponding to the busbar L2 after the current temperature compensation, and the temperature value T3c corresponding to the busbar L3 after the current temperature compensation to the existing two-bus system through the two-bus communication circuit 103;

[0098] T2c=T2p+ΔTh+ΔTte+ΔThr;

[0099] T3c=T3p+ΔTh+ΔTte+ΔThr.

[0100] After the system is powered on, the temperature detection device automatically operates in low-power mode. The temperature detection device is awakened periodically by the microprocessor unit 100 and enters normal operation mode. After completing the temperature compensation process, the microprocessor unit controls the power supply of all sensors to be turned off and enters sleep mode itself, waiting for the next awakening.
