一、概况杭州市有85个厂矿企业配备308台高频设备,直接操作人员600余人。其中高频感应加热设备112台,占36％。主要为C_1、C_2、C_3、C_(30)C_(60)。仿苏型、拉管焊接、电子管行业排气封口设备等类型。普遍用于淬火、焊接、拉管、排气、封口等工艺过程,我们先对高频感应加热设备进行治理。统一用浙江省建德县无线电厂生产的RJ-2型近区场强仪进行测试(定期作仪器校正),按国内暂行参考标准电场强度20V/m、磁场强度5A/m执行,以实际操作位的头、胸、腹部测得的最大值为准,但从设备检验角度来讲,对机壳缝隙、仪表、调谐手轮中心、馈线等是以探头距离设备5cm为准。我们对每台设备现场使用情况、防护设施以及操作人员身
First, an overview Hangzhou has 85 factories and mines with 308 high-frequency equipment, direct operation of more than 600 people. Including high-frequency induction heating equipment 112 units, accounting for 36%. Mainly C_1, C_2, C_3, C_ (30) C_ (60). Imitation Su-type, pull pipe welding, vacuum tube sealing industry, and other types of equipment. Commonly used for quenching, welding, pipe pulling, exhaust, sealing and other processes, we first high-frequency induction heating equipment for treatment. Unified with the radio plant in Jiande County, Zhejiang Province RJ-2 type near field strength meter test (regularly as instrument calibration), according to the domestic interim reference standard electric field strength of 20V / m, magnetic field strength 5A / m implementation, the actual operation The head, chest, abdomen measured the maximum whichever is the most, but from the equipment inspection point of view, the chassis crevices, instruments, tuned hand wheel center, feeders and so on are based on the probe distance equipment 5cm. We use each device on site, protective equipment and the operator
