Referring to fig. 1-2, an electrical fire monitoring probe 100 of the present application, the electrical fire monitoring probe 100 is connected to a circuit breaker 200 to detect the circuit breaker 200. The circuit breaker 200 is provided with an inlet port 201 and an outlet port 203. The inlet port 201 of the circuit breaker 200 is provided with two inlet conductors 202. Two outgoing conductors 204 are provided at the outlet 203 of the circuit breaker 200. The electrical fire monitoring probe 100 is connected to one of an inlet port 201 and an outlet port 203 of the circuit breaker 200.
Specifically, the electrical fire monitoring detector 100 includes: a probe housing 10, a current data detector 20, a voltage and temperature sensing element 30, a circuit board 40 and a data transmission port 50. Wherein the sonde housing 10 is connected to a circuit breaker 200. Two parallel detection holes 111 are formed in the detector housing 10, and the two detection holes 111 are respectively used for two incoming wires 202 or outgoing wires 204 of the circuit breaker 200 to pass through. The current data detector 20 is disposed in the detector housing 10, and respectively sleeved on the incoming wire 202 or the outgoing wire 204 passing through the detection hole 111 on the detector housing 10 for detecting current data, such as current and leakage data, on the incoming wire 202 or the outgoing wire 204. The voltage and temperature sensing member 30 is inserted into a socket 205 provided on the inlet port 201 or outlet port 203 of the circuit breaker 200 to sense voltage data and temperature data on the inlet conductor 202 or outlet conductor 204. The circuit board 40 is disposed within the probe housing 10 and is electrically connected to the current data detector 20 and the voltage and temperature detecting member 30. The data transmission port 50 is used to connect a data line and transmit data detected by the electrical fire monitoring detector 100 to an external device through the data line.
Thus, the electrical fire monitoring detector 100 is a single, unitary component that is simple in construction and occupies a small amount of space. Which plugs directly into the circuit breaker 200 to detect data in the conductor. In the present application, the electrical fire monitoring detector 100 is plugged into the outlet port 203 of the circuit breaker 200.
In a preferred embodiment, the sonde housing 10 includes a body 11 and a cover 12.
Specifically, the body 11 has a mounting cavity 112 formed therein. The current data detector 20, the circuit board 40 and the data transmission port 50, and at least a portion of the voltage and temperature detecting member 30 are disposed within a mounting cavity 112 formed in the body 11. The cover 12 closes one end of the opening of the body 11.
Wherein the body 11 is provided with two cylindrical portions 113. The detection hole 111 is formed in the cylindrical portion 113. The lid 12 is provided with a through hole 121 at a position facing the cylindrical portion 113.

In a preferred embodiment, the voltage and temperature sensing element 30 is two male copper strips 31.
Specifically, the plug copper piece 31 has one end connected to the circuit board 40 and the other end protruding from a groove formed on the cover 12 to insert the circuit breaker 200. The extending direction of the portion of the plug copper piece 31 located outside the probe case 10 is parallel to the central axis direction of the detection hole 111. Thus, the insertion direction of the electrical fire monitoring detector 100 is the same as the extension direction of the wires, facilitating the installation thereof.
In a preferred embodiment, the plane of the circuit board 40 is perpendicular to the central axis of the detection hole 111.
The circuit board 40 is perpendicular to the central axis of the detection hole 111, so that the size of the electrical fire monitoring probe 100 in the insertion direction can be reduced.
In the present application, the data lines are 485 buses. The 485 bus is connected to the data port 50 at one end and to the communications gateway at the other end.
