80kV可攜式全自動絕緣油耐壓測試器 TOR-80

該裝置是根據IEC 60156、ASTM D877、ASTM D1816標准設計的，用於測量變壓器絕緣油和其它絕緣液體的介電強度。

它是一個全自動的設備，可以按照這些標準中規定的程序進行測試，也可以按照設置選單中相應部分規定的用戶自定義程序進行測試。

工作原理

該裝置的核心是產生高壓源變壓器和電子控制模組。該裝置的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。

電壓升高由微控制器通過控制逆變器進行管理。而控制逆變器是由裝置內的控制模組所指揮。

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。

The unit is designed to measure the dielectric strength of transformer oil and other dielectric fluids according to IEC 60156, ASTM D877, ASTM D1816.

It is a fully automatic device that allows testing according to the procedures defined in these standards, as well as according to the user procedures specified in the appropriate section of the setup menu.

Operating principle

The core of the unit is the high voltage transformer and electronic modules. The unit operates by gradually increasing the voltage on the secondary winding of the high voltage transformer from zero to the maximum voltage, or to the voltage at which an electric breakthrough occurs in the dielectric fluid in the measuring cell installed on the high voltage contacts of the transformer.

The voltage in the secondary winding of the transformer occurs due to gradual increase of voltage in the primary winding supplied with sinusoidal voltage from the control inverter, one of the electronic modules.

Voltage increase is managed by a microcontroller through the control inverter. The control inverter is commanded by the unit control module.

During operation, AC (50-60Hz) voltage is supplied from the secondary winding terminals through the cell electrodes into the dielectric fluid in the measuring cell. The breakthrough occurs between the electrodes in the space filled with the dielectric fluid.
