Ingantaccen Zafi na Tushen Yankin da Koyarwa na Insulatoci/Bushing

Haddadin Yawanci:

1. Yawan Inganta ko Koyarwa na Tushen Yankin:

• Muhimman Tsari: Inganta tushen tsari kamar gaba, zafi, yanayi, da kuma shirya (a yankunan masana).

• Takardun Aiki: Shiga bayanai game da aikin insulatoci na baya, sama da abubuwan da suka faru, kama, da kuma zafi.

• Binciken A Filin: Yi bincike a filin don tabbatar da alamomin daga cikin insulatoci, sama da tracking, erosion, da kuma zafi na rubuce-rubuce.

2. Zabbar Da Sakamako da Koyarwa na Creepage:

• Koyarwa na Creepage: Daga tushen yankin, koyara distance na creepage don inganta aikin insulatoci.

• Zabbar Sakamako: Zabi sakamoko insulatoci wanda ya ba da hanyar leakage mai kyau da kuma ya yi girma a kan yankin. Sakamokon alternating shed sun fi yawa wajen inganta hanyoyi mai kyau.

3. Zabbar Da Labarin Testoni da Koyarwa na Testoni:

• Testonin Gaba: Yi labarin testoni a makarantar don inganta aikin insulatoci a kan gaban tsari.

• Testonin Hydrophobicity: Inganta aikin insulatoci na hydrophobic, wanda ya iya taimaka wajen inganta flashover a filin.

• Testonin Stress Masu Kyau: Inganta aikin insulatoci na kyau, musamman idan an zaɓe insulatoci masu kyau ko mafi girma.

4. Tabbatar Da/Koyarwa na Sakamakon:

• Labarin Field: Saka wasu insulatoci a filin da kuma tabbatar da aikinsu lokacin rike.

• Koyarwa: Daga bayanai labarin, koyara sakamakon insulatoci ko material.

Bi Koyarwa Don Koyarwa Insulatoci/Bushing:

1. Koyarwa Insulatoci Na Baki Da Distance Mai Kyau Na Creepage:

• Mafi girma da cost mai kyau saboda leakage paths mai kyau.

• Za buƙata koyarwa structural don inganta insulatoci mai girma.

• Za buƙata downtime a lokacin installation.

• Ba da aikin tafin da inganta distance mai kyau na creepage.

• Ya iya inganta aikin system da kuma koyarwa cost mai kyau.

• Ayoyi:

• Abubuwa:

2. Installation of Additional Creepage Boosters/Extenders:

• Ba zan ba da aikin tafin kamar insulatoci masu creepage mai kyau ba.

• Za buƙata koyarwa cikin a kan installation don inganta bonding da performance.

• Cost-effective solution compared to replacing entire insulators.

• Minimal installation downtime, as the boosters can be added to existing insulators.

• Flexibility to change the shed profile, improving resistance to water bridging.

• Creepage boosters/extenders are polymeric skirts coated internally with a specially formulated compound. When heated, the skirt shrinks around and bonds onto the existing insulator sheds, increasing the effective diameter and creepage distance.

• Description:

• Advantages:

• Disadvantages:

Water Bridging and Shed Profiles:

• Water Bridging: A continuous path of contaminated conductive moisture that can cause arcing and flashover. This is a common issue in polluted environments, especially when insulators have uniform shed profiles.

• Alternating Shed Profiles: By using insulators with alternating shed profiles, the risk of water bridging is significantly reduced. The irregular shape of the sheds disrupts the formation of continuous moisture paths, enhancing the insulator's performance in wet and contaminated conditions.

Visual Representation:

The provided image shows insulators with creepage boosters/extenders installed in a substation. These boosters increase the effective creepage distance and shed diameter, improving the insulator's ability to resist flashover and arcing in harsh environmental conditions.
