Problems solved by technology

[0007] 3. There is leakage in the equipment line;
[0008] 4. Electrical fire caused by excessive line temperature
[0009] In order to popularize science and standardize the use of electricity, various forms of electrical fire warning demonstration boxes have appeared on the market. However, they generally only have a single function and require professionals to demonstrate. The operation is cumbersome and the use itself is not safe.

Embodiment approach 1

[0047] Turn on the electrical equipment (analog) that is in the state of leakage, select the appropriate working gear for the electrical equipment, and make it in the working state. The electrical fire monitoring detector 1 generates a residual current alarm, and at the same time, the circuit breaker 2 is disconnected through the relay control; this In this case, the electrical fire monitoring detector 1 is set in cooperation with the second live wire 32 and the neutral wire 4 through the residual current transformer 7. This is a conventional power consumption environment, but in the demonstration, the insulation work should be done well and the access control should be controlled. Voltage;

Embodiment approach 2

[0049] Turn on the normal electrical equipment, select the appropriate working gear for the electrical equipment, and make it in the working state. The electrical fire monitoring detector 1 generates a residual current alarm, and at the same time, the circuit breaker 2 is disconnected through the relay control; in this case, the electrical The fire monitoring detector 1 is set only in cooperation with the second live wire 32 through the residual current transformer 7, which is an unconventional power consumption environment and only simulates the existence of residual current.

[0050] In the present invention, the working principle of the high-temperature alarm demonstration unit is to approach the temperature sensor 10 with a safe heat source. When the temperature sensor 10 detects that the temperature exceeds the threshold, the electrical fire monitoring detector 1 generates a high-temperature alarm, and at the same time, the circuit breaker 2 is controlled by a relay. disco...

Abstract

The invention relates to a multifunctional electrical fire early warning demonstration box, which is characterized in that an electrical fire monitoring detector is arranged in the demonstration box, and an arc fault simulation demonstration unit, an overcurrent alarm demonstration unit, a residual current alarm demonstration unit and a high temperature alarm demonstration unit are arranged in cooperation with the electrical fire monitoring detector; the arc fault simulation demonstration unit, the overcurrent alarm demonstration unit and the residual current alarm demonstration unit are matched with a live wire and a zero wire through a circuit breaker, and a control switch is arranged between the circuit breaker and the electrical fire monitoring detector in a matched mode. The defect that the demonstration box can only perform single demonstration is overcome, the operation is convenient, safe and practical, the demonstration box is suitable for non-professional personnel to perform power utilization propaganda science popularization, the situations of fault arcs, illegal power utilization, electric leakage and too high temperature existing in a line in actual power utilization can be demonstrated separately, demonstration is not interfered with one another, the operation is simple and safe, only different power utilization devices need to be selected, demonstration can be completed without operation of professionals, and science popularization of electricity utilization safety education can be realized.

Description

technical field [0001] The present invention relates to the technical field of education or demonstration appliance; appliance for teaching or communicating with blind, deaf or mute; model; planetarium; globe; map; Background technique [0002] Electrical fires generally refer to the heat energy released due to faults in electrical circuits, electrical equipment, appliances, and power supply and distribution equipment, such as high temperature, arc, electric sparks, and non-faulty energy released, such as the hot surface of electric heating appliances. Fires caused by igniting the body or other combustibles under burning conditions, including fires caused by lightning and static electricity. [0003] At present, electrical fire accidents continue to occur frequently and present an increasing trend year by year. [0004] The main causes of electrical fires include: [0005] 1. The aging of the equipment lines caused by the lack of maintenance for many years, resulting in ar...
