Embodiment
Below by being further described the invention by reference to the accompanying drawings.The concrete scheme described in the following examples is only the content in order to the invention is described, and is not used in the restriction to the invention.
A kind of Non-connecting ring main unit that the invention provides as shown in figures 1 to 6, comprise cabinet door 1 and cabinet 2, 3 space bars 21 are extended with forward from rear wall in described cabinet 2, cabinet 2 is separated into 4 space cavity be connected by both sides by described space bar 21, these 4 space cavity from top to bottom can respectively as bus-bar room 3, breaker chamber 4, relay bungalow 5 and cable vault 6, described 4 space cavity are connected with 4 air outlets 22 on the rear wall being positioned at described cabinet 2 respectively, described air outlet 22 is all communicated with a blower fan 8 by the air channel 7 be positioned at outside described cabinet 2 rear wall, the sidewall of described cabinet 2 is also provided with some dust-proof dust-removing mouths 23, enter for preventing dust or the discharge of dusty gas.
The rear wall of described cabinet 2 is also provided with incoming line 27, for the inlet wire of bus cable.
Described cabinet door 1 is also provided with some transparent observation windows 11, is convenient to the ruuning situation that the moment observes equipment in cabinet 2.Described cabinet door 1 can carry out hinged preferably through hinge or rotating shaft with described cabinet 2.
Described dust-proof dust-removing mouth 23 preferably at least arranges one in each space cavity both sides, the both sides up and down of described dust-proof dust-removing mouth 23 are also symmetrically arranged with slot 24, described slot 24 is fixed on the outside of the sidewall of described cabinet 2, and in described slot 24, coupling is provided with plate 25 slidably.
