Electrical Safety
★Exhibit Content: Electrical safety knowledge and simulation of overload, excessive contact resistance, and short circuit faults ★Interaction: Electromechanical interaction + multimedia presentation ★Operation: 1. Press the corresponding "Start" button to enter the overload experiment, excessive contact resistance experiment, and short circuit experiment respectively; 2. Select the simulated appliance or button to connect, and observe changes in current, temperature, and light operation; 3. Combine with multimedia explanations to understand the hazards of electrical faults. ★Exhibit Description: The exhibit consists of a square platform, transparent protective cover, 32-inch display screen, circuit demonstration panel, simulated electrical components, indicator lights, and function button set. It is a recommended exhibit from the KexMall exhibit store. The tabletop is divided into three electrical safety experiments: the overload experiment allows appliances to be connected one by one to observe changes in line current and temperature; the excessive contact resistance experiment compares circuit differences between good and poor contact; the short circuit experiment involves sequentially inserting the light plug and fan plug to observe circuit reactions under short circuit conditions. Through button operations and multimedia explanations, visitors can intuitively understand common electrical risks such as leakage, overload, poor contact, and short circuits, enhancing safety awareness. ★Scientific Principle: When current passes through a conductor, heat is generated. Excessive total power, poor line contact, or short circuits can cause abnormal current increases and local temperature rises, potentially leading to electrical fires and equipment damage. Protective devices such as leakage protectors, fuses, and air switches can promptly cut off the circuit when faults occur, preventing accidents from escalating. The exhibit visualizes abstract principles of current, resistance, and safety protection through simulated experiments, helping visitors understand safety standards for household, laboratory, and public electrical use, and master basic methods to prevent electrical accidents.
