The beneficial effects of the utility model are: this system adopts the matrix form thunder and lightning surge protector of B level; bring reliable assurance for the lightning protection of chopped-off head power-supply system; the single module lightning protection of comparing has characteristics such as anti-lightning impulse current is big, residual voltage is low, long service life; eliminate and solved the hidden danger and the defective of unborn lightning protected aspect, outdoor communication base station, make communication security that reliable guarantee arranged.
Description of drawings
Fig. 1 is the structural representation of communication base station lightning protection power-supply system of the present utility model.
Fig. 2 is the matrix form thunder and lightning surge protector schematic diagram that adopts in the example.
Embodiment
Further describe specific embodiment of the utility model below in conjunction with accompanying drawing:
Consider that calculator room equipment power supply load is bigger, it is convenient to reach operation and maintenance for the sake of security, and the utility model is selected the lightning protection device of parallel connection type thunder and lightning surge protector as power-supply system for use.When selecting lightning protection for power supply; because there are actual conditions such as unsteadiness, the fluctuation range of voltage are big in China's electrical network; when selecting the lower thunder and lightning surge protector of residual voltage, must consider that also the thunder and lightning surge protector of being installed has sufficiently high maximum continuous operation voltage as far as possible.If maximum continuous operation voltage is on the low side, then easily cause lightning protection device owing to long-term work at the deviation value of normal power source the deterioration damage takes place.
Communication base station lightning protection power-supply system of the present utility model as shown in Figure 1, realizes lightning protection by parallel connection type thunder and lightning surge protector is installed in the AC distribution panel 10 of this power-supply system.Wherein, this parallel connection type thunder and lightning surge protector adopts specified through-current capacity at 60kA, and maximum through-current capacity is installed in the low-voltage distribution side 11 of AC distribution panel 10 at the matrix form thunder and lightning surge protector 20 of 150kA (8/20 μ S).
This matrix form thunder and lightning surge protector 20 has inefficacy separator 21, when losing efficacy, can be automatically and the power-supply system disconnection, and do not influence the normal power supply of the power supply system for communications.In addition, matrix form thunder and lightning surge protector adopts the project organization of multicomponent array, can prolong useful life, and can effectively reduce residual voltage with the impulse current mean allocation to each element arrays in parallel.Preferably, matrix form thunder and lightning surge protector also needs to have anti-flaming function, can not be on fire when decreasing in inefficacy or deterioration.Monitoring for convenience, management and maintenance in the future; can select to have the matrix form thunder and lightning surge protector that fault alarm is indicated, the remote measurement port function also can be provided; for example; can adopt BP8-60-4B type matrix form thunder and lightning surge protector; as shown in Figure 2; wherein L1, L2, L3 are meant phase line of power respectively, and N is meant the zero line of power supply, and PE is meant earth connection.
