Tabia ya mfumo wa kipimo cha joto kwa switchgear

1. Positioning characteristics. The optical fiber of the system is not only a Sensor ya joto but also a channel for information transmission. Due to its good insulation characteristics and flexibility, it can be directly laid on the surface or key parts of a live equipment to obtain real-time temperature data of the operating equipment. Wakati kosa la overheating hutokea, mfumo unaweza kutoa kengele na kwa usahihi Machapisho nafasi overheating, thereby guiding maintenance work.

2. Tabia za usambazaji. The system can continuously and dynamically monitor temperature changes at points every 2 meters within a range of several thousand meters, and can set temperature alarm values arbitrarily. The monitoring system host can carry multiple 2-kilometer-long optical fibers.

3. Maendeleo. The system is the most effective means of online temperature monitoring in the power system, and has replaced traditional linear temperature sensing materials in foreign countries. It has become mature in technology. The monitoring system host can easily debug, programu, Na set parameters such as temperature measurement eneo, urefu, and alarm points through the Windows operating interface.

4. Usahihi. Azimio la joto la mfumo hufikia 0.1 ℃ and the temperature accuracy is ± 1 °C. The laser emission device inside the monitoring system host emits tens of thousands of light pulses per second and outputs the average sampled temperature to the display system, effectively eliminating random errors.

5. Kubadilika. The system provides continuous dynamic monitoring signals and can achieve alarms through two settings: kwanza, multi-level temperature point alarms can be set, kama vile kengele ya awali 30 °C, pre alarm at 40 °C, na hatua zilizochukuliwa saa 50 °C, na inaweza kurekebishwa kulingana na mazingira tofauti; The second is to set a temperature change rate threshold based on the high temperature change rate before the accident occurs. When the temperature change rate is detected to be greater than this value, an alarm signal is issued and corresponding signal output is provided. The monitoring system immediately generates an alarm when one of these two alarm conditions is met. The monitoring system can adjust the sampling interval according to on-site requirements.

6. Scalability. The system can be extended to multiple optical fibers, and automatic optical path selection and measurement can be achieved by adding an optical path switching switch. The monitoring system can be expanded to a maximum of 8 nyuzi za macho.

7. Utangamano. The system can be interconnected with other intelligent measurement and control devices such as PC, fire alarm system, SCADA, Nk. through RS232 interface, built-in relay contacts, and other output forms. Katika maombi ya ulinzi wa moto, inaweza pia kuunganishwa kwenye mfumo wa kidhibiti cha kengele ya moto ili kutoa mawimbi ya kengele. Mfumo wa ufuatiliaji unaweza kutoa mawimbi katika sehemu na viwango kulingana na kanda tofauti za kengele, ambayo inaweza kukabiliana na mahitaji ya madhumuni tofauti ya udhibiti.

8. Usalama. ya mfumo ina kipengele cha rekodi ya usalama, ambayo inaweza kuhifadhi data zote za kihistoria tangu mfumo ulikuwa unafanya kazi. Ikiwa fiber ya macho imeharibiwa, mfumo wa ufuatiliaji unaweza kupata sehemu iliyoharibiwa na ina kazi ya uchunguzi binafsi. Mfumo wa ufuatiliaji hautatoa mwingiliano wa sumakuumeme na nyaya za nguvu kwa sababu ya matumizi ya mawimbi ya macho na media zisizo za conductive. – nyuzi za macho.
