2.1 Hukumomin Tashin Bincike Da Fanni Masu Amfani

Amfani da hukumo na bincike na rarrabe an yi wa tasiri mai yawa. Hukumo na bincike na rarrabe yana nemi daga cikin tashin bincike na kayan tasiri na uku na rarrabe:

• Kayan tasiri na biyu da kadan (X terminal) da kayan tasiri na uku da biyar.

• Kayan tasiri na tsari da kayan tasiri na biyu da biyar.

• Kayan tasiri na takam da gidaje.

2.2 Binciken Abubuwan Da Ba Sun Zama Ba A Hukumo Na Rarrabe

Hukumo na rarrabe yana da uku abubuwan da ba su zama ba:

• Iya Karamin Kayan Tasiri: Yana nuna kayan tasiri na uku na X terminal da kayan tasiri na biyu da biyar. Saboda kapasitar da ya kunshi wannan ƙasa ya kai 1000pF, wanda yana da damar da wasu ƙasa (da dama da picofarads), ba zan iya nuna hayar kayan tasiri na uku da biyar ba.

• Kayayyakin Tasiri Da Dama: Tsarin kayan tasiri na gidaje da kayan tasiri mai tsari ya kai da damar. An yanayi kayan tasiri na 2000V, amma a nan da za a yi 1600V (wasu ƙungiyoyi sun yi 2500-3000V. Saboda haka za a iya nuna ruwan da ya samu kayan tasiri, amma kayayyaki na dama ta yi ma'ana ga kayan tasiri).

• Rabobi: Rabobi na terminal board da kuma small porcelain sleeve da aka fitar da shi ne a kan X terminal zai kasance kayan tasiri. Idan an amfani da hukumo na tsakiya za a iya rage damar (hukumo na tsakiya yana nuna kayan tasiri na uku na X terminal da kayan tasiri na biyu da biyar), amma kayan tasiri na hukumo na tsakiya yana da damar.

Idan an nuna, tasiri mai yawa da kuma tasiri mai yawa suna da fanni masu daidai. Tsarin basu yana da uku ƙasa: core, primary winding, da secondary winding. Tasiri mai yawa na musamman yana da muhimmiyar inganta tasiri, tare da kuma inganta tattalin tattalin kayan bayanai da kuma babbariyyar inganta. Ya kamata a lura cewa tasiri mai yawa suna da muhimmiyar inganta tattalin tattalin kayan bayanai. Wannan abubuwa ne ke nuna cewa tasiri mai yawa suna da damar da kusa. A nan da za a yi amfani da tasiri mai yawa ta hanyar baya. Diagram mai nuna fanni masu amfani da tasiri mai yawa yana cika a Figure 1.

Daga diagram, primary winding na tasiri mai yawa ana sauka da wasu hukumomin a kan primary circuit. Kayan tasiri na biyu ana da alamar da kayan tasiri na tsari. Tsarin kayan tasiri na biyu da kayan tasiri na tsari shine rated transformation ratio, yawanci K_n = U₁/U₂. Primary winding na nisa ana sauka a kan primary circuit, saboda haka biyu ba zan iya dogara ba - dogon dogon zai gina kayan tasiri da ya fiye, zai taimakawa tasiri da kuma line. Daga baya, a lokacin bincike, za a duba secondary winding, iron core, da kuma housing don in inganta tattalin tattalin tasiri da kuma kayan bayanai.

Wannan irin wiring mode yana amfani da two single-phase transformers don in nuna kayan volts a kan phases. Amma, ba zan iya nuna kayan volts a kan ground ba. Ana amfani wannan irin wiring mode a kan power grids da suka da volts da 20 kV da kadan inda neutral point ba a duba ko kuma arc-suppression coil a duba.

4.3 Y0-Y0 Wiring

Wannan irin wiring mode yana amfani da both the primary and secondary sides of the single-phase transformer into the Y0 type. Wannan irin wiring mode yana da muhimmiyar lafiya, tare da kuma amfani da meters da kuma relays da suka bukata kayan volts, da kuma insulation monitoring meters. Ana amfani wannan irin wiring mode a kan systems da suka da volts da 35 kV da kadan.

5 Bincike Amfani Da Precautions A Cikin Binciken Yanayi Na Outdoor Voltage Transformers

• A cikin binciken yanayi, ana bukata a yi scientific treatment and testing of the polarity and insulation resistance measurement of the voltage transformer. Wannan yana taimakawa in inganta tattalin tattalin voltage transformer.

• Wiring na outdoor voltage transformer yana da muhimmiyar lafiya. Ana bukata a yi parallel connection between the primary winding and the circuit under test, and the secondary winding and the voltage coils of the connected measuring instruments and relay protection devices. Ana bukata a yi correct polarity.

• A cikin binciken yanayi, load on the secondary side of the voltage transformer ba zan iya kai rated capacity. Idan yake kai, za a iya nuna data error.

• Secondary side of the voltage transformer ba zan iya short-circuited. Saboda haka, za a duba secondary winding, iron core, da kuma housing. Ana bukata a yi installation of certain protection and monitoring equipment on the primary side to ensure the stability of the entire test system and avoid unnecessary situations.

• A cikin binciken yanayi, za a duba secondary winding at one point. Wannan yana taimakawa in inganta tattalin tattalin kayan bayanai da kuma safety of relevant experimental personnel.

6 Nema

A nan da an yi binciken yanayi na outdoor voltage transformers, ana bukata complete and scientific test methods and precautions. Wannan yana taimakawa in inganta tattalin tattalin binciken yanayi, protect the safety of equipment and personnel, and provide a reliable foundation for the application of outdoor voltage transformers in the power supply field to maximize their value.
