100 kV可攜式全自動絕緣油耐壓測試器 TOR-100

TOR-100絕緣油耐壓測試器是用來測試變壓器絕緣油和其它液體電介質的擊穿電壓裝置，並符合IEC 60156, VDE 0370, ASTM D877, ASTM D1816, IRAM 2341標準。亦有考慮到客戶的需求以及新版本標准出現時，它可進行任意的補充和編輯。

工作原理

該裝置的工作核心是產生高壓源變壓器和電子控制模組。其工作原理是將高壓變壓器二次繞組上的電壓從零逐漸增加到最高電壓，或安裝在變壓器高壓接點上的測量單元中的絕緣油發生崩潰擊穿時的電壓。
變壓器二次繞組的電壓是由於一次繞組的電壓逐漸增加而發生的，一次繞組的電壓是由電子控制模組中控制逆變器所提供的正弦波電壓。在操作過程中，AC（50-60Hz）電壓從二次繞組終端通過測量單元的電極供應到絕緣油中。擊穿過程就發生在充滿絕緣油的兩端電極之間。

優勢

• 自動準確測量高達100 kV的擊穿電壓。
• 閃絡時極短的關斷時間4μs。
• 內建列表機，測量結束後可以列印測量結果。
• USB介面用於隨身碟的測試結果存取。
• 操作簡單，易於維護。

TOR-100 tester is designed to determine the electrical breakdown voltage of transformer oil and other liquid dielectrics in accordance with IEC 60156, VDE 0370, ASTM D877, ASTM D1816, IRAM 2341. This list of standards may be supplemented and modified both with customer preferences taken into consideration and as new versions of standards become available.

Principle of operation

The working core of the tester is a high-voltage transformer and electronic modules. The principle of operation of the device is to gradually increase the voltage on the secondary winding of a high-voltage transformer from zero to maximum value, or to a value at which there will occur a breakdown of a liquid dielectric poured into a measuring cell installed on the high-voltage contacts of the transformer and constituting a part of its output electrodes.

A voltage rise at the high-voltage contacts of the secondary winding of the transformer occurs due to a gradual increase in the voltage on the primary winding when sinusoidal voltage is applied thereto from a controlled master inverter.
