| 1、在双母线运行时，应考虑当母联开关跳闸后，保证被分开的两个系统至少应有一台变压器中性点接地； 1. When two buses are running, it should be considered that when the bus switch trips, at least one transformer neutral grounding should be ensured for the two separated systems. 2、变压器中、低压侧有电源时，则变压器中性点必须直接接地，以防止高压侧断路器跳闸，变压器成为中性点绝缘系统； 2. The neutral point of the transformer must be grounded directly to prevent the circuit breaker from tripping and the transformer becomes the neutral point insulation system when there is power supply in the middle and low voltage side of the transformer. 3、发电机—变压器—线路组的主变压器中性点应保持接地运行。 3. The neutral point of the main transformer of the generator transformer line group should be kept grounded. |
