The special installation equipment that machine ark, frame regards the equipment such as server, switching equipment as, having a few identical index demands. Emerge besides uninterrupted power supply, report defend, be struck by lightning defends outside, still ask power source receives electrical outlet of plug-in unit ——— , have small temperature rise (25 ℃ ) , prevent insert by accident, insert Kong Fang to protect, high accuracy is inserted unplug, housing is tall flame retardant (850 ℃ ) wait for rigid index, among them index of ” of “ temperature rise is a the most important.
” of “ temperature rise is to show in socket the circumstance of full load plays set up an electric circuit one hour, each terminal is in socket the degree with the elevatory temperature after electrify. According to the requirement of national level GB2099.1GB2099.3, the temperature rise index of common and eligible electrical outlet should not prep above 45 ℃ . If temperature rise index exceeds 45 ℃ , socket can produce overheat inevitably in use process, crust is out of shape, cause fire danger feeling. It is under 25 ℃ , just accord with a requirement.
So, the discretion that what element is affecting temperature rise index be?
Above all, the metal inside socket used cupreous material.
Different cupreous capable person guides the difference with a performance very big presence, the bronze of high grade stannum that uses in order to break through place of bodyguard electrical outlet is exemple, because its contain cupreous volume to be as high as 65% , the 4—5 that the price also is common copper material times; Next, the size of area of cupreous material cut. Cut area is larger, guide epicene better, temperature rise is smaller also; The 3rd, means of inside wire connection also can affect temperature rise. The copperplate of an organic whole that place of breakthrough bodyguard electrical outlet uses nods connection without solder, reduce temperature rise namely efficient way; The 4th, the sleeve accuracy and flexibility, tight ness rating that contacts with plug also can affect socket temperature rise. The contact is more close together, temperature rise is smaller.
Another factor that affects temperature rise is the dimensional design with interior electrical outlet. Have many electrical outlet in the market now appearance looks small and exquisite, but sacrificed however the reasonable space with interior electrical outlet, go against caloric to send out. Breaking through what bodyguard electrical outlet uses is design of ultralow temperature space, in make sure exterior is beautiful while, interior stays have come loose enoughly hot space, because socket is long,can avoid effectively to work, in-house and accumulative quantity of heat is exorbitant and cause housing to change model
