Operation and application of detonators
2021-09-08In daily life, it is necessary to use blasting technology when demolishing large buildings or mining ore. This involves a device called an detonator to control the explosion. Today we will explore the mysteries behind this.
Detonator, also known as detonator, refers to the electrical device used in blasting engineering that causes the melting of connected detonator bridge wires and initiates explosions by outputting large currents or sparks. It is mainly divided into power generation and capacitance type.
Operating procedures for detonators:
1、 Repairers of explosive devices must undergo technical training, hold valid certificates, and be familiar with the "Coal Mine Safety Regulations", "Coal Mine Mechanical and Electrical Equipment Maintenance Quality Standards", "Coal Mine Mechanical and Electrical Equipment Intactness Standards", and relevant standards and regulations for explosion-proof electrical equipment.
2、 Inspect and record the faults of the detonators that need to be repaired in this class, conduct regular performance parameter tests on the detonators, and master the structural performance and repair process of the detonators.
3、 When repairing the detonator, the capacitor should be fully discharged first, and then the components should be repaired or replaced.
4、 The replaced components should meet the requirements of the "Quality Standards for Maintenance of Coal Mine Mechanical and Electrical Equipment".
5、 Test the insulation resistance of the equipment and dry the affected equipment.
6、 It is strictly prohibited to conduct short circuit tests on two wiring terminals. To avoid damage to electrical components and equipment.
7、 After maintenance, the detonator must undergo a burst energy and discharge time test, and can only be used after passing the test.
8、 The repaired detonator must comply with the "Coal Mine Mechanical and Electrical Equipment Integrity Standards" and relevant standards and regulations for explosion-proof electrical equipment.
9、 Carefully fill out the maintenance records.
Detonators are now proficiently used in fields such as mine construction, bridge construction, building demolition, and military, with a certain degree of economy, reliability, and flexibility.
That's all we need to know about detonators. If we encounter demolition of buildings that require blasting, we don't have to panic too much. Because the construction personnel have already undergone precise calculations, the probability of accidents occurring is very low.
