Abstract
The utility model relates to a three-phase linked switch box, belonging to the field of a power supply system in a moving communication base station. For the power supply system in the moving communication base station, in order to prevent the communication blocking as the equipment in a communication machine room is damaged due to the oversize voltage surge caused by an external power-supply grid, the input end of an AC distribution plate with a power cable being connected in a machine room needs to be additionally provided a three-phase linked switch that can prevent heavy current. In the three-phase linked switch, wires are connected in the three-phase fire-wire system, and a heavy-current three-phase air switch is arranged in a cuboid box body. The power cable enters from the top of the box body and is connected with the wire incoming end of the three-phase air switch. When the current of the power supply is enlarged suddenly, the three-phase air switch can be cut off automatically, so as to protect loading equipment and avoid the damage to the loading equipment due to the excess external current. Therefore, the three-phase linked switch box can be used in the power supply system in the moving communication base station.

Technical field
The utility model belongs to electric power system field, mobile communication base station, particularly a kind of three-phase linked switch case.
Background technology
The present present situation of the power power-line leading-in end of mobile communication base station is: a part of base station electric power system is directly to be received the three-phase air switch input of the A.C. distribution box of base station by the air switch of owner's end; Some base station is three-phase air switch input and the three phase mains lightning arrester (GPB) that is connected to A.C. distribution box through a 200A disconnecting link.
But because the uncertainty of the air switch capacity of owner's end, in case owing to the excessive voltage that the reason of externally fed electrical network causes is impacted, very easily cause the damage of communications equipment room equipment and make Communication Block, not only cause damage, also can produce certain negative effect society to commmunication company.
Generally hold and draw a power power-line on total output switch separately and be connected to interchange distribution plate input in the machine room, like this owner's end and inside of base station power supply are all had protective effect from the owner.But do not get rid of through the owner yet and agree that base station power line leading-in end and owner hold the master switch upper end in parallel.This kind situation must install the three-phase linked switch that prevents big electric current in the electric power system of base station additional with regard to requiring, and forbids the power power-line leading-in end of base station AC distribution panel to hold the master switch lower end directly in parallel with the owner, to guarantee the base station power system safety.
The mobile communication base station electric power system block diagram that installs the three-phase linked switch additional as shown in Figure 1.The three-phase alternating current civil power always exports switch through the owner and the three-phase linked switch is powered to the AC distribution panel of base station, and alternating current obtains direct current through rectifier rectification and powered and charge a battery to communication apparatus by the DC control screen.The three-phase linked switch is big current hollow air cock, three phase mains lightning arrester (GPB) and air switch interlock protection power-supply system.Typical Disposition mobile communication base station total electricity capacity mainly is made of rectifier power capacity and air-conditioning power capacity, other parts comprise that base station intraoral illumination equipment electricity consumption and transmission equipment directly are connected alternating current or connect small-sized rectifier earlier, directly to the transmission equipment power supply, power consumption all can be ignored by small-sized rectifier.The 1.5-2 that the capacity of the big current hollow air cock that installs additional must satisfy base station total electricity capacity doubly insures capacity.
The utility model content
The purpose of this utility model installs the three-phase linked switch additional in order to solve in the background technology, a kind of three-phase linked switch case is provided, it is characterized in that, casing 1 profile is a cuboid, chamber door 2 left sides flexibly connect with the left front limit of hinge and casing 1, and door switch 3 is installed on the right part of chamber door 2; Three-phase linked switch inside is the three-phase five-wire mode line, insulating cement plank 5 is installed on the middle in the casing 1, three-phase air switch 4 is installed in the middle of the insulating cement plank 5, the zero line row 8 and ground wire row 7 left and right sides that are installed on respectively in the casing 1, three copper busbars 9 of A, B, C three-phase are installed in three-phase air switch 4 belows, be electrically connected with three-phase air switch 4 three-phase leading-out terminals respectively, power power-line 6 enters from casing 1 top, is connected on the lead-in wire terminal of three-phase air switch 4.
The beneficial effects of the utility model are installed in the three-phase air switch automatic disconnection in the three-phase linked switch case for when the electric current of electrical source of power increases suddenly, and the protection load equipment is avoided the excessive destruction to load equipment of foreign current.
