Temporary Electricity Safety Common Sense

Temporary electricity refers to the design, installation, use, maintenance and removal of low-voltage power systems using electric equipment and lighting on the production and construction sites during temporary overhaul or maintenance and engineering construction. The main facilities and materials for temporary power utilization include transformers, power distribution cabinets, distribution boxes, switch boxes, cables, wires, electrical tools, electric tools, lighting fixtures, electrical equipment, etc. Basic management requirements for

temporary power consumption:

temporary power consumption organization design shall be prepared for the construction site with 5

or more temporary power consumption equipment or the total capacity of equipment is 50kW or more. 2.

Temporary electricity consumption organization design must follow the "

preparation, review and approval " procedure, which shall be organized and compiled by electrical engineering technicians and implemented after being reviewed by relevant departments and approved by the technical director of the enterprise with legal personality. 3.

Temporary power consumption project shall be constructed according to the design drawing, and shall be jointly accepted by relevant units before being put into use after being qualified.

Temporary electricity use must establish safety technical files, which shall be established and managed by electrical technicians. Among them, "

electrician installation, inspection, maintenance and demolition work record " can be assigned to be managed by an electrician, which shall be reviewed and approved by the main person in charge or project manager every week, and shall be filed uniformly after the temporary power consumption project is demolished. 5.

Temporary power consumption shall be checked regularly, potential safety hazards shall be handled in time, and rechecked and accepted.

and Class II

metal shell hand-held electric tools, the rated leakage action current of the leakage protector shall not be greater than 15mA , and the rated leakage action time shall not be greater than 0.1s . 3.

When operating in wet places and on metal frames, Class II

or Class III hand-held power tools powered by safety isolation transformers must be selected. 4.

It is strictly forbidden to use Class I

hand-held electric tools in wet places or on metal frames. 5.

The load line of the water pump must adopt waterproof rubber sheathed copper core flexible cable. Any damage and joints are strictly prohibited, and no external force is allowed.

Peak's "Centennial" Ideal

Editor's note: During the National Day, the "Jinhua New Observation" column of Jinhua TV Station launched a series of reports on "National Day New Observation: New Development of Old Enterprises" to understand the new developments of those old enterprises that have grown up with New China in the new era. October 3 broadcast of the "peak of the 'centennial 'ideal", about the development of the peak group and the future direction of development. The "century" ideal of the peak Jinhua TV reporter Wang Dujuan Jiang Qian host: speaking of Zhejiang Jianfeng Group Co., Ltd., Jinhua people are no stranger. The older generation of Jinhua people are more familiar with, may be the predecessor of Jianfeng Group-Jinhua Cement Factory. Open the first old photo 58 years ago, surrounded by mountains and a rice field in the middle. Old Jinhua can see at a glance that this is the Wise Temple, 8 kilometers north of Jinhua City and east of the former Zhuangtou of Luodian Town. In August 1958, the first group of pioneers came here and built Jinhua's first cement factory on a desolate hillside of 16.94 mu with a pair of hands and warm blood. From the earliest cattle-drawn ball forming machine to the electric ball forming machine, from pure manual labor to machine substitution, it took 26 years of hard work. By 1983, the annual output of peak cement reached 120000 tons, the output value was 6.75 million yuan, and the profit was 2.4 million yuan. In these 26 years, the cement plant has experienced a difficult period of the country, and the ten-year catastrophe of the "Cultural Revolution" has finally ushered in a good time of reform and opening up with tenacious vitality, laying the foundation for steady development in the future. Looking at these old pictures,
