国产2005型X射线探伤机的控制箱,在操作上存在以下缺点: 由于采用手动操作,升、降电压速度不易控制,不易满足高压变压器升、降电压的操作要求;在射线作业过程中,随着电源电压波动,要不断地手动调节管电压和管电流,尤其当作业现场电源电压波动频繁时,进行这种操作更加困难;当射线探伤机连续工作太久,绝缘油温升高,使温度控制接点断开,或曝光完毕,在15～20秒钟内未手动降压回零位时,均采取高压自动跳闸,从而增加了由于高压跳闸而引起的操作过电压冲击次数,高压变压器绝缘容易受到损伤;射线管加上高压时,射线机上只有一个不太明显的灯
Domestic 2005 X-ray flaw detector control box, there are the following shortcomings in the operation: As a result of manual operation, rising and falling voltage speed is not easy to control, it is not easy to meet the high-voltage transformer rise and fall of the operating requirements of the voltage; With the fluctuation of the power supply voltage, it is necessary to constantly adjust the tube voltage and the tube current continuously, especially when the power supply voltage fluctuates frequently on the job site. When the radiographic flaw detector works continuously for too long, the temperature of the insulating oil increases, When the control contact is disconnected or the exposure is finished, the high-voltage automatic tripping is taken when the voltage is not manually reduced to zero within 15 to 20 seconds, thereby increasing the number of over-voltage operation caused by the high-voltage tripping. The high-voltage transformer is easily insulated Subject to damage; when the tube is pressurized, there is only one less obvious light on the ray machine
