Description
本創作係關於一種比壓器用之屏蔽環，尤指一種改善比壓器進行檢測時產生的部分放電之比壓器檢測用之屏蔽環。 The present invention relates to a shielding ring for a specific pressure device, and more particularly to a shielding ring for detecting a partial discharge which is generated when a specific voltage is detected by a specific pressure device.
比壓器一般用於電力系統，電力系統上的高電壓使用範圍相當廣泛，由於高電壓不易直接以電表量測或控制，所以通常會使用比壓器來將高電壓轉換成低電壓，再配合電表來測量，或者將低電壓提供給儀器或保護電驛，對電力系統可達到保護及監控的效果。 The comparator is generally used in power systems. The high voltage range on the power system is quite extensive. Since the high voltage is not easy to measure or control directly with the meter, the comparator is usually used to convert the high voltage into a low voltage. The meter can be used to measure, or provide a low voltage to the instrument or protect the power, which can achieve protection and monitoring effects on the power system.
一般來說，比壓器剛出廠時為了要確保品質，首先會經過檢測儀器的檢測，以確保比壓器的功能正常；檢測儀器會與比壓器作連接，藉由檢測儀器上的儀表來觀察比壓器的放電值；但從檢測儀器上儀表的數值得知，比壓器的放電值高於正常數值，導致品管判定為不合格，經過不斷測試後，判定其原因為外部接線或是干擾所造成的部分放電，而造成所檢測出的放電值出現異常。 In general, when the pressure regulator is just shipped from the factory, in order to ensure the quality, it will first pass the detection of the test instrument to ensure that the function of the comparator is normal; the test instrument will be connected with the comparator, by detecting the instrument on the instrument. Observe the discharge value of the pressure comparator; but from the value of the instrument on the test instrument, the discharge value of the pressure comparator is higher than the normal value, which causes the quality control to be judged as unqualified. After continuous testing, the cause is determined to be external wiring or It is a partial discharge caused by interference, which causes an abnormality in the detected discharge value.
為了克服上述技術之問題，本創作的目的係提供一種比壓器檢測用之屏蔽環，可改善比壓器檢測時所產生的部分放電問題，以使比壓器檢測出的放電值正常。 In order to overcome the problems of the above techniques, the object of the present invention is to provide a shielding ring for detecting a specific pressure device, which can improve the partial discharge problem generated when the specific pressure device is detected, so that the discharge value detected by the specific pressure device is normal.

屏蔽環係裝設於該第一高壓側及該第二高壓側之上方，且將該接線端子穿過該屏蔽環之固定孔，使該屏蔽環能鎖固於該第一高壓側及該第二高壓側；當比壓器進行檢測時，檢測儀器藉由外接線與該接線端子作連接；該屏蔽環使外部電場可達到屏蔽的效果，能使電場緩和，避免受到外部的干擾以及尖端放電的產生。 The shielding ring is disposed above the first high voltage side and the second high voltage side, and the terminal is passed through the fixing hole of the shielding ring, so that the shielding ring can be locked to the first high side and the first The high-voltage side; when the comparator is inspected, the detecting instrument is connected to the terminal by an external wiring; the shielding ring enables the external electric field to achieve the shielding effect, can relax the electric field, avoid external interference and tip discharge The production.
