This EPS emergency power supply 1 just is being widely used in hospital, numerous people such as market and underground air defence work are many but outlet is few, in the limited building of lamp, can EPS emergency power supply 1 operate as normal will greatly have influence on the people's lives and property safety like this, particularly the most of province of Deposits in Eastern Coastal China is area with more lightning activities, and lightning energy produces high-strength surge, high-strength surge meeting causes the charger 11 in the EPS emergency power supply 2, inverter 14, system controller 16, battery check device 13, status displays 17 and actuation means 18 etc. damage and can't operate as normal, will make EPS emergency power supply 1 to work like this and have lost emergent effectiveness.
At above-mentioned defective, the applicant makes further research EPS emergency power supply 1, has this case to produce then.
The utility model content
The purpose of this utility model is to provide a kind of EPS emergency power supply of anti-thunder and lightning, the problem of being damaged by thunder and lightning generation surge to solve the EPS emergency power supply that is installed in the area with more lightning activities coastal cities in the prior art.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of EPS emergency power supply of anti-thunder and lightning comprises the EPS emergency power supply with input, and wherein, the EPS emergency power supply of described anti-thunder and lightning also comprises the Surge Protector that is connected between input power supply and the input.
The EPS emergency power supply of aforesaid a kind of anti-thunder and lightning, described Surge Protector are the tandem Surge Protector, and this tandem Surge Protector one end links to each other with the input power supply, and the other end links to each other with input.Can be applied for the tandem Surge Protector like this.
The EPS emergency power supply of aforesaid a kind of anti-thunder and lightning, described Surge Protector are parallel Surge Protector, and this parallel Surge Protector one end links to each other with the input power supply, and the other end links to each other with ground.Can be applied for parallel Surge Protector like this.
The EPS emergency power supply of aforesaid a kind of anti-thunder and lightning also is provided with safeties between described EPS emergency power supply input and the Surge Protector.When big surge is passed through, can directly make the EPS emergency power supply be protected like this by the mode that disconnects safeties.
As a kind of preferred mode, these safeties are fuse.
After adopting said structure; owing between the input of input power supply and EPS emergency power supply, also be connected with Surge Protector; this Surge Protector can digest part enters into the EPS emergency power supply from the input power supply surge; thereby increased the validity of EPS emergency power supply, and then reduced because the loss that sudden power etc. cause.
