Rated operating frequency HZ50
Alarm contacts and other configurable applications are mainly used in various industrial sound indoor and outdoor environments, rated operating voltage AC220V/AC380V, frequency 50/60HZ, DC voltage DC220V, rated current to 630A distribution network for equipment maintenance or preparation Use electricity to provide the appropriate power connector. Products with overload, short circuit, leakage protection and other functions, are widely used in industry, chemicals, food, airports, terminals, ships, metallurgy, power plants, medical Liao, construction and other industries. According to the installation method: portable type, clear box type, concealed type, back panel combined type; according to the cabinet shell material points: die-cast aluminum alloy, engineering plastic, cold-rolled steel plate, stainless steel.
Mainly reflected:
1. The inspection of the explosion-proof distribution box does not meet the requirements of the standard:
Most manufacturers do not test the shell, especially the cast iron shell material; the pressure test of the flameproof shell also exists in name only, from the whole inspection to the sampling inspection, and some are simply not detecting, not playing the hydraulic pressure; the blisters on the flameproof surface, the pores Seriously exceed the standard; some of the fasteners on the flameproof enclosure are not fastened securely. 2. The process of the explosion-proof distribution box does not meet the requirements of the standard, such as the unevenness of the level of the explosion-proof surface, and the non-coated arc resistance in the explosion-proof cavity. paint.
3. The explosion-proof structure of the explosion-proof distribution box does not meet the requirements of the standard:
If no internal or external grounding terminals are provided; electrical clearances and creepage distances are small; excess steel inlets are not provided with steel blocking plates or replaced with paper blocking plates; the width or matching gap of the flameproof surface exceeds the standard, and the explosion-proof surface The seal gasket is arbitrarily added between the two; the hardness of the rubber sealing ring used in the introduction device does not meet the requirements; the shell of the die-casting product for which individual enterprises do not comply with the standard requirements.
4. The material of the explosion-proof distribution box does not meet the requirements of the standard:
For example, the grades of aluminum alloy shell materials do not meet the requirements of the standard, and some companies even use scrap aluminum or miscellaneous aluminum die-casting shells to earn higher profits; some brands of cast iron shell materials do not meet the requirements; nameplate materials Does not meet the standard requirements.
For China's explosion-proof distribution box market, the explosion-proof distribution box quality problems mainly reflect the above four. In order to prevent the purchase of unqualified explosion-proof power distribution box products, you will be reminded of the explosion-proof power distribution box. When purchasing explosion-proof power distribution boxes, you should try your best to cooperate with large companies, such as the explosion-proof, so as to effectively avoid the purchase of unqualified products.
