The technical requirements for electrical circuits in dust and fiber hazardous environments of explosion-proof operation columns are basically the same as those for electrical circuits in gas and vapor hazardous environments of corresponding levels, that is, electrical circuits in Zone 10 and Zone 11 can be considered as Zone 1 and Zone 2 respectively. Overcurrent protection, short circuit protection, overvoltage protection, undervoltage protection, instantaneous power outage protection, and phase failure protection. Stainless steel plate: Stainless steel has corrosion resistance, high explosion-proof and impermeable properties. At the same time, stainless steel products have a complete structure, beautiful appearance, and easy surface cleaning, making it an ideal choice for explosion-proof equipment casings. Zone 2: An environment where it is impossible for a mixture of gases to occur during normal operation, or where a mixture of gases is only present for a short period of time if it does occur. The following three conditions must be present simultaneously: the presence of vapor or mist of flammable gases or liquids; The frequency can be manually adjusted. A process curve that can set the speed to change over time. The DCS system can also provide signals to control its frequency. （Zhejiang 304 stainless steel explosion-proof operating column manufacturer）

product structure

1. For the explosion-proof structure, the steel plate is welded with a shell and the surface is electrostatically sprayed with plastic;

2. Equipped with high breaking miniature circuit breakers or molded case circuit breakers, AC vacuum contactors, motor protectors, voltmeters and other components, it has overload, short circuit, undervoltage, phase loss, leakage and other protection functions.

3. Both incoming and outgoing lines are equipped with spark free explosion-proof plug-in devices and have clear equipment tag number indicator boards.

4. The explosion-proof surface adopts special processing methods, embedded with oil resistant aging silicone "0" - shaped sealing rings, to achieve a protection level of IP65 for the box body, in order to solve the problem of rainwater entering the traditional explosion-proof box for outdoor use, and to eliminate the complex and ineffective measures of traditional rainproof covers.

5. All fasteners are made of corrosion-resistant 304 stainless steel fasteners.

6. It can be installed in a hanging or vertical manner according to on-site needs.

7. Specific functions and appearance can be customized according to user requirements. （Zhejiang 304 stainless steel explosion-proof operating column manufacturer）

Explosion proof operation columns should be considered for laying electrical circuits in locations with low risk or far distance from the release source. For example, when hazardous gases or vapors are heavier than air, electrical circuits should be laid at heights, while cables should be directly buried underground or filled with sand in cable trenches. When the hazardous gas or vapor is lighter than air, electrical circuits should be laid at a lower location, and cables should be laid in cable trenches. Introduction to Explosion proof Power Distribution Box: Explosion proof lighting distribution box is mainly suitable for power circuits with a voltage of 380V. The box can be equipped with small circuit breakers of 3P or 4P, as well as plastic shell switches, according to user needs or supply drawings. To avoid potential hazardous temperatures, the allowable current carrying capacity for hazardous environments should not be higher than that for non hazardous environments. The selection of insulation wire cross-section and electrical cable cross-section in Zone I and Zone 2 should ensure that the allowable current carrying capacity of the conductor is not less than 1.25 times the rated current of the fuse and the set current of the circuit breaker's long-term overcurrent release.

Features:
1. Cast aluminum alloy shell, surface sprayed with plastic.

2. The direction and specifications of the inlet can be freely selected by the user.

3. Both steel pipes and cables can be used for wiring.

4. When selecting, users should clearly specify the specifications, quantity, and orientation of the inlet and outlet lines

Gas mixture hazardous areas: Zone 1, Zone 2. 2. Gas mixture: IIA, IIB, IIC.

The product can be equipped with (main switch) plastic case circuit breakers, small circuit breakers (with overload and short circuit protection functions), AC contactors, thermal relays, signal lights, buttons, switches, and other components such as Schneider, Chint, Delixi, ABB, etc. It has reliable explosion-proof and electrical performance.

The internal wires of the explosion-proof lighting power distribution box are cold pressed with OT terminal blocks and insulated with sleeves. The terminal blocks are fastened with special anti loosening tile pads to ensure the stability and safety of electrical performance.

Most instruments are not explosion-proof and cannot be directly exposed to the outside, which does not meet explosion-proof standards. Therefore, the manufacturer chooses to open an instrument sized hole on the door panel of the explosion-proof box and fix it internally with a meter frame. The direction of the inlet varies greatly, and the inlet can be selected according to user requirements. DQM series cable sealing joints can be directly installed according to user requirements. In locations with low risk or far distance from the release source, consideration should be given to laying dedicated electrical circuits. For example, when hazardous gases or vapors are heavier than air, electrical circuits should be laid at heights, while cables should be directly buried underground or filled with sand in cable trenches. When the hazardous gas or vapor is lighter than air, electrical circuits should be laid at a lower location, and cables should be laid in cable trenches.

The frequency conversion speed control box for electric motors can adjust the speed of ordinary three-phase asynchronous motors by changing their output frequency, in order to meet the requirements of production processes or achieve energy-saving purposes. The energy-saving rate can reach 30% -60%. Introduction to explosion-proof power distribution boxes: Explosion proof lighting distribution boxes are mainly suitable for power circuits, with a voltage of 380V and small circuit breakers of 3P or 4P installed in the box. Plastic shell switches can also be installed, and detailed information can be provided according to user needs or drawings. The direction of cable entry and exit can be made into various forms according to user requirements, such as upward and upward, upward and downward, downward and downward, and downward and upward. The inlet and outlet adopt pipe threads and are equipped with cable clamping and sealing devices. Both steel pipes and cable wiring can be used. In order to solve this problem, explosion-proof cable reels are equipped with opening and closing indicators on the pins of the cable reel. When designing the plug, the grounded end should be longer than the main contact. In this way, when inserting into the socket, the end of the connector is connected first, and when unplugging, the grounded end is disconnected later. In addition, there are interlocking devices installed on the plugs and sockets, which can only be plugged in and unplugged after ensuring a power outage. This avoids the generation of sparks and static electricity. It can display frequency, speed, load rate or current digitally. Is the explosion-proof instrument box we commonly use in compliance with explosion-proof standards? Of course it is. Because we have installed explosion-proof glass and sealed the openings.
