Problems solved by technology

[0002] At present, junction boxes are usually used in the erection and construction of power grid transmission. The traditional junction box has a relatively simple structure and does not have other safety protection functions except for insulation and waterproofing.
In addition, due to the increase in people's activities, there is a demand for electricity, and safety accidents such as fires often occur at cable connections due to excessive power, resulting in property losses.

Embodiment 2

[0047] see Figure 8 As shown, a control method for a cable fireproof junction box includes the following steps:

[0048] SS01: Turn on the power switch 401, the MCU control chip controls one connector 2 to be turned on, which is the working state, and the other connector 2 is disconnected, which is the idle state;

[0049] SS02: The temperature sensor monitors the temperature of the connector 2 in the working state, and transmits the temperature data to the MCU control chip;

[0050] SS03: The MCU control chip compares the temperature of connector 2 in the working state with the combustible temperature of the cable;

[0051] SS04: When the temperature of the connector 2 in the working state is lower than the flammable temperature of the cable, the connector 2 maintains the current working state, and the MCU control chip controls the indicator light 402 to light up;

[0052]SS05: When the temperature of the connector 2 in the working state is higher than the flammable temper...

Abstract

The invention discloses a cable fire protection junction box and a control method thereof, and relates to the technical field of cable wiring. The cable fire protection junction box comprises a box body, wherein a power switch, an indicator lamp I and an indicator lamp II are arranged on one surface of the box body; holes are arranged in the two sides of the box body; a dustproof pad is fixed in each hole; connectors are fixed to the bottom surface of the interior of the box body; a horizontal partition board is arranged in the box body; a lead penetrating hole is arranged in one surface of the partition board; a plurality of fixing seats are fixed on one surface of the partition board; one surface of the fixing seat is connected to a control board; and a power source is fixed on one surface of the partition board. The two connectors are arranged in the junction box, and the temperature of the connectors is monitored, when the temperature of one connector is too high, working is stopped and the other connector is replaced to work; through a way of cycle working and relaxation, the temperature is reduced while the cable is smooth, and a fireproof effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of cable connection, and in particular relates to a cable fireproof junction box and a control method thereof. Background technique [0002] At present, junction boxes are usually used in the construction of power grid transmission. The traditional junction box has a relatively simple structure and does not have other safety protection functions except for insulation and waterproofing. In addition, due to the increase in people's activities, there is a demand for electricity, and safety accidents such as fires often occur at cable connections due to excessive power, resulting in property losses. Contents of the invention [0003] The purpose of the present invention is to provide a cable fireproof junction box and its control method. By setting two connectors in the junction box and monitoring the temperature of the connectors, when the temperature of the connectors is too high, stop working and replace an...
