How to embed the civil air defense fuse box and need help?

Method:

1. Embed a junction box at both ends of the civil air defense wall.

2. The junction box is explosion-proof and can accommodate the fuse.

3. After the fuse is installed, it should be plugged with fireproof mud and covered with a cover plate (the cover plate is fixed by four bolts).

4. For details, please refer to the civil air defense electrical construction method.

There is no requirement to install a fuse on the side of the civil air defense area for the lighting line leading from the civil air defense area to the non-civil air defense area, but it must be transferred out through a closed junction box (for the method, please refer to the "Installation of Electrical Equipment in the Air Defense Basement").

Overview:

Low-voltage power distribution system.

The fuse is a kind of electrical appliance that plays a role in safety protection, the fuse is widely used in power grid protection and electrical equipment protection, when the power grid or electrical equipment occurs a short circuit fault or overload, it can automatically cut off the circuit to avoid damage to electrical equipment and prevent the spread of accidents.

The fuse is composed of an insulating base (or support), a contact, a melt, etc., the melt is the main working part of the fuse, and the melt is equivalent to a special wire connected in series in the circuit, when the circuit is short-circuited or overloaded, the current is too large, and the melt melts due to overheating, thus cutting off the circuit.

The melt is often made in the form of filaments, grids, or sheets. The melt material has the characteristics of low relative melting point, stable characteristics and easy fuse. Generally, lead-tin alloy, silver-plated copper sheet, zinc, silver and other metals are used.

Dear, I'm glad to answer for you: the practice of pre-embedding the civil air defense fuse A: Hello dear The practice is as follows:

1. Embed a junction box at both ends of the civil air defense wall. 2. The junction box is explosion-proof and can accommodate the fuse. 3. After the fuse is installed, it should be plugged with fireproof mud and covered with a cover plate (the imitation plate of the cover field bench is fixed by four bolts) 4. For details, please refer to the civil air defense electrical construction atlas.

1) The fuse box is embedded in the civil air defense, and the fuse is maintained in the distribution cabinet fuse. (2) Protective closed junction box, the thickness is not less than the galvanized steel plate welded, and the thickness of the cover plate is greater than 3mm. Song Fiber (3) Fuse:

The lighting line leading from the civil air defense area to the non-civil air defense area is separately provided with a fuse embedded box on the inside of the protective airtight door. The fuse is commonly known as the fuse tube, the fuse is the fuse in the glass tube, which is an overcurrent protection electrical appliance, and the fuse is mainly composed of two parts of the melt and the fuse tube and the external filler. When in use, the fuse is connected in series in the protected circuit, when the current of the protected circuit exceeds the specified value, and after a certain period of time, the heat generated by the melt itself blows the melt, so that the circuit is disconnected, and plays the role of protection.

In the commonly used fuse of the delay fuse, the fuse can be seen through the transparent glass tube in the form of a spiral, while the fuse of the ordinary fuse is similar to a thin copper wire. The fuse device of some electric vehicles does not use a fuse, but uses a (low-voltage) circuit breaker (also known as automatic switch, air switch), it is a kind of switch that will trip as long as there is a short circuit, the switch will trip when it forms a circuit, and it uses air to extinguish the arc generated during the switch. (Low voltage) circuit breakers are divided into two categories: broken assembly type and broken 10,000 type

Break-mounted type is device-type automatic air circuit breaker; The breaker type is a universal (also known as frame) automatic air circuit breaker. The circuit breaker (low-voltage) is composed of five parts: contact installation, arc extinguishing device, tripping mechanism, transmission device and protection device. When the current exceeds the rated value for a certain period of time, the (low-voltage) circuit breaker will automatically jump (i.e. trip) to the off position, cut off the circuit, and protect the battery and motor.

If you are satisfied with my service, please give a thumbs up, and once again wish you all the best! Peace and joy!

Is the fuse box connected to the light on the top?

What kind of lights, lights?

Yes, aren't they all mostly switched on and off by now?

The box of the fuse should be connected to **.

It should be connected in series at the live wire position before the switch.

Just connect the switch?

Yes, you can try, there are very few fuses to protect the lamp now, and it generally does not need to be protected by a fuse.

This one is installed behind the civil air defense door.

It's generally a circuit breaker or something.

In wartime, when the lighting circuit in the basement of the civil air defense is short-circuited, the electric bell in the fuse box will ring, which can play a certain warning role. Then his monopoly is to say that this Kai has the effect of anti-corrosion, moisture-proof, high-temperature resistance, and early state calling.

Extended information: The embedded human anti-fuse box generally includes the following steps: 1. Anzheng installation pit:

Holes are drilled in the embedded locations and then fixed with special inserts to secure the fuse box, while ensuring that the drain is not affected. 2. Install the inlet pipe: connect the external power harness to the inlet terminal of the civil air defense fuse box and check whether the wiring is correct.

3. Place the civil air defense fuse box in the embedded hole: put the bracket of the civil air defense fuse box into the embedded hole and install it, and ensure that the lifting and rolling stop is completely disconnected from the external power supply, and take necessary protective measures to prevent the outside world.

Whether to add a closed junction box to the installation of a fuse in civil air defense.

Want. There is already a closed box for the line pipe to penetrate the anti-human wall, whether to add a closed box to the fuser?

No need.
