Embodiment Construction

[0013] Such as figure 1 , figure 2 As shown, a fire-resistant electrical cabinet includes a cabinet body 1, a cabinet door 7, the cabinet door 7 is hinged on the cabinet body 1, a waterproof platform 2 is provided at the bottom of the cabinet body 1, and a water leakage hole 10 is provided on the outside of the waterproof platform 2, which can effectively Prevent rainwater from entering the cabinet through the cabinet door. When the rain is too heavy, the accumulated water will be left from the leak hole, which has better waterproof function and stronger practicability; a transparent observation window 3 is set on one side of the cabinet body, so that the inside of the electrical cabinet can be observed The working status of the instrument, and the situation in the electrical cabinet at all times. The door lock of the cabinet door 7 is an electronic control anti-theft lock and / or an electronic card swiping lock. The electronic control anti-theft lock is controlled by a remote...

Abstract

The invention relates to a fire-resistant electrical cabinet, which comprises a cabinet body and a cabinet door, wherein the cabinet door is hinged on the cabinet body, the cabinet body is composed ofan outer shell, an inner shell and a fire-resistant layer, the fire-resistant layer is arranged between the outer shell and the inner shell, the outer shell and the inner shell are made of aluminum alloy base plates, the fire-resistant layer comprises fire-resistant ceramic fibers and thermosetting resin, the fire-resistant ceramic fibers comprises 4-8 parts of polyester fiber, 4-8 parts of chromium oxide, 5-7 parts of sodium dodecyl sulfate, 6-11 parts of carbon fibers, 5-6 parts of hydroxyethyl cellulose, 6-8 parts of filler, 6-8 parts of diatomite, 1-5 parts of triethanolamine, 6-10 partsof ethylene bis stearamide, 8-13 parts of 3-chlorobenzaldehyde glycine Schiff base, 3-6 parts of Kanuma mud, 7-10 parts of zirconia, and 2-5 parts of a potassium hydroxide solution being 20% in mass concentration. The fire-resistant electrical cabinet has the advantages of high strength, impact resistance, corrosion resistance and thermal insulation performance, and good fireproof effect.

Description

technical field [0001] The invention relates to the field of distribution cabinets, in particular to a fire-resistant electrical cabinet. Background technique [0002] According to the "Code for Fire Protection of Building Design" GB50016-2014, regarding the fire resistance ratings of factories, warehouses and civil buildings, the flammability and fire resistance limits of building components with different fire resistance levels are stipulated. According to the fire resistance level of building components, the floor limit should not If it is less than 1.5h, the fire resistance of the beam and column roof load-bearing components should not be less than 2h, 3h and 1.5h respectively. It can be seen that the importance of the fire resistance of building components in the event of a fire. [0003] The fire-resistant requirements of building fire-fighting electrical equipment are important facilities to ensure the fire safety of buildings and the safety of people's lives and prop...
