Overvoltage ta musamman ya gina danganta a zanfarin substation. Amfani da amfani na rayuwa suna karamin hanyar zanfari na transformer electromagnetic, kafin misoperations na circuit breaker ke gina overvoltage a cikin grid, wanda ya gina karamin hanyar zanfari na transformers da devices.

2. Tekunoloci na Distribution Transformers

2.1 Microcomputer Protection

A takaice da tashin tekunoloji, microcomputer protection (microcomputer-based) na da inganci/reliability/selectivity/sensitivity, wanda ke da data na system a lokacin da aka fara. CPU/ROM/flash/RAM protection system ta da kyau a takaice da power storage da efficiency. Flash/ROM suna yi nasara wajen samun CPU capability don daidaito masu yawa, wanda ke haɗa comms/protection/monitoring/measurement don control na automation.

2.2 Data Acquisition Components

Daga baya da 14-bit AVD converter (synchronous type) da multi-channel filter, wannan component na da inganci/stability/low power/fast conversion na transformers. Internal high-precision chips suna yi daidaito na errors ba a yi amfani da abubuwa na gaba. CPU system na da 16 preset/10 external output switches (10 power GPS, 5 monitor operation) da 24V regulator. Precision clock ta da kyau a takaice da GPS pulse reception.

2.3 Trip Component Modules

Classified as trip/logic relays, trip modules integrate multi-relay functions (closing holding/manual trip/trip current/protection) in 0.5A/1A specs. Valve parameter adjustments don’t require relay replacement. CPU-driven logic relays connect to closing intermediates, with closed negative power supplies preventing switch-induced transformer damage and reducing maintenance costs.

4. Amfani da Data Acquisition Component

Data acquisition component ana da 14 - bit precision AVD converter da inganci masu kyau da filter circuit da multi - way switches. Idan, 14 - bit precision AVD converter shine sabon ƙungiyar da ake gina da synchronous circuit. Saboda haka, amfani da data acquisition component don daidaito na transformer na da inganci masu kyau, stability masu kyau, low power consumption, da kuma fast conversion speed.

Bisa ga haka, a cikin measurement na system na data acquisition component, ba a tabbas da amfani da abubuwa na gaba. Duk daidaito na errors a cikin power operation za su iya daidaito ta hanyar chip na built-in da inganci masu kyau. Kuma, data acquisition component na da input da output functions masu mutanen. CPU system na data acquisition component na da 16 preset switches, 10 external output switches, da kuma 24V regulated power supply switch. Ta haka, ita ce za su iya amfani da 10 external output switches don bayyana power na GPS a cikin system. Masu biyu na 5 switches suna da manufar daidaito da supervision and control na operation status na data acquisition component.

A karshe, an setta clock circuit na data acquisition component, wanda ya takaice da clock chip da take da inganci masu kyau, saboda haka za su iya daidaito protection device na transformer don bayyana GPS pulse signal.

5. Tashin O&M na Distribution Transformers

5.1 Yadda Ake Sanya O&M Management

Yawan karamin distribution transformers suna nuna daidaito da management daidai. Saboda haka, ake sanya O&M na equipment: address defects/hazards da kuma amfani da procedures, kuma daidaito failur prevention. Inspections/maintenance na regular na kyau don daidaito safe operation da kuma identify issues da kalmomi.

5.2 Yadda Ake Sanya Configuration na Protection

Install lightning arresters don daidaito overvoltage-induced internal short circuits, kafin test insulation resistance da kalmomi don daidaito burnout. O&M personnel na da kyau a zama da selection na fuse elements da low-voltage overcurrent settings.

5.3 Standardize Relay Protection O&M

Inspections/maintenance na regular na kyau don daidaito reliable relay protection operation, wanda ke muhimmiyar don stability na power system. Steps include: understanding equipment initial states, analyzing operational data, and adopting new technologies to maintain scientific O&M.

Secondary cables in strong EM fields make non-electrical protection sensitive to interference, risking false trips. Countermeasures:

5.4 Enhance Secondary Cable Protection

• Protect external connections (e.g., gas relays), seal cable entrances, and add rain shields.

• Use shielded cables; separate AC/DC laying.

• Anti-interference measures: delay settings, 55% - 70% UN operating voltage, and voltage adjustment under symmetric DC insulation.

• Route cables away from high-voltage/control lines; ground shielded cables at both ends.
