Electricity safety of park entertainment equipment
by：Jinma Rides 2022-01-05
At present, many amusement equipment in parks need electricity to maintain operation, so we must pay attention to safety in the use of electricity, so what should we pay attention to in the use of electricity?
一. Electrical system
The design function of the electrical system of park amusement equipment must meet the requirements of operation control and safety protection of the amusement equipment, and meet the requirements of normal use under local environmental conditions.
2. Low-voltage power distribution system
The grounding type of the low-voltage power distribution system of park amusement equipment should adopt the TN-S system; the metal shell of electrical equipment and the non-charged metal structure must be reliably grounded; the protection repeated grounding resistance of the low-voltage power distribution system is not more than 10 ohms; grounding The design and construction of the device should meet the requirements of the 'Grounding Design Code for Industrial and Civil Power Installations'; the insulation resistance between the live circuit and the ground should not be less than 1M ohm.
Three, install lightning rod
Amusement park equipment with a height of more than 15m should be equipped with lightning protection devices. The lightning protection devices must be connected reliably, and their grounding resistance should not be greater than 10 ohms.
I sincerely hope that everyone can play in a safe environment of park amusement equipment!
