| 1.在高压熔断器柜的弧线,它的设计,以防止子阶段的错误。 1. The arc of the high-voltage fuse cabinet is designed to prevent sub-stage errors. 2. 一旦分相短路会引起的相位误差。 2. Phase error caused by short circuit. 3.非开放和关闭的变电站,共减少,巴士总站变量段计数器应禁止使用弧 3. The number of non-open and closed substations is reduced altogether. Arc should be prohibited in variable section counter of bus terminal. 微机消谐装置这些因素都会对消弧柜的确定故障相产生一定的误差,因此,在使用的时候应该谨慎一些,使得误差减小,增加精准性。 These factors of the computer harmonic elimination device will cause certain errors in determining the fault phase of the arc suppression cabinet. Therefore, caution should be taken when using this device to reduce errors and increase accuracy. 在使用继电保护试验电源,我们应该注意以下几个方面： In the use of relay protection test power supply, we should pay attention to the following aspects: 1.继电保护试验电源的供电方式是交流220V； 1. The power supply mode of relay protection test power supply is AC 220V. 2.装置正负极对应负载设备的正负极,不能接反哦,以免损坏仪器设备； 2. The positive and negative poles of the device correspond to the positive and negative poles of the load equipment, and can not be connected with the negative poles, so as to avoid damaging the instrument and equipment; 3.使用过程中应保持电源左右两侧的空气对流 畅通,附近不应有其他物体阻挡空气的对流循环； 3. The air convection on both sides of the power supply should be maintained smoothly during use, and there should be no other objects nearby to block the air convection cycle. 4.使用结束后,先断开负载、然后断开电源开关,接着在关闭仪器。 4. After use, first disconnect the load, then disconnect the power switch, and then turn off the instrument. |
