電圧試験方法のための改良に関する。[Detailed Description of the Invention] The present invention relates to a closed type switchgear using a highly insulating gas (for example, SF 6 gas), and in particular to an on-site withstand voltage test that facilitates an on-site withstand voltage test after assembly is completed. Concerning improvements for test methods.

据付けされるものが多くなつて来ている。 This type of sealed switchgear is characterized by a structure that does not expose live parts. On the other hand, in order to improve the reliability of sealed opening/closing devices, recent devices of this kind are assembled in a completed or partially assembled state at an assembly factory, and then transported to the site in that state.

れている。 For this reason, it is difficult to apply voltage from a power source for on-site withstand voltage tests in closed type switchgears whose live parts are not exposed. Applying voltage through the cables of substation equipment is usually impossible because it requires a large capacity of the power supply. Therefore, at present, voltage is applied by boosting the voltage from the low-voltage side using the instrument voltage transformer used in sealed switchgear, or by using the cable entry port of the sealed switchgear to create a special short voltage transformer. A method is adopted in which the test power supply is connected via a paddle cable.

完了する。 A grounding shield 11 surrounds this internal element to reduce the potential gradient. The low voltage coil is connected to the secondary terminal box 12. A tank 13 surrounds all of these. Since this transformation device is only used for on-site withstand voltage tests, it can be made extremely compact. Since this device is only used for on-site withstand voltage tests, it can be made extremely small. FIG. 3 is an explanatory diagram of how the test transformation device is attached to the main body of the sealed switchgear, and is an explanatory diagram of the installation situation for a three-phase circuit. 3
The structure is such that three sets of test transformers 5 are connected by a phase bus 14. The action will be explained below. In the on-site withstand voltage test, as shown in Figure 3, a specified voltage is generated on the high voltage side by exciting the test transformer from the low voltage side, and the voltage is applied to all parts via the 3-phase bus for a specified period of time. The on-site withstand voltage test was completed.
