Surge Protector is connected in parallel in circuit, and while only having lightning current to flow through, lightning protection device can instantaneously become normally open, the lightning current of releasing, and be nanosecond operate time.Although Surge Protector can be released these lightning currents; but the impact of lightning current may be not only single; after lightning current impacts; Surge Protector damages and arrives before lightning current impact next time; do not have in time Surge Protector to be repaired, lightning current still can affect the protected equipment in rear end.
Summary of the invention
The utility model provides a kind of surge protector redundant system for solving the technical problem existing in known technology.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is: a kind of surge protector redundant system, comprises main surge protector and first order redundant electric surge protector unit; Described first order redundant electric surge protector unit comprises first order surge protector for subsequent use and first order relay; The end of incoming cables of described main surge protector is electrically connected with the phase line of protective circuit by fuse, the leading-out terminal of described main surge protector and earth electrode electrical connection; One end of described first order relay coil is electrically connected with the end of incoming cables of described main surge protector, and the other end is electrically connected with working zero line; Connecting after the normally-closed contact and fuse of described first order relay successively in the end of incoming cables of described first order surge protector for subsequent use, is electrically connected with the phase line of protective circuit; The leading-out terminal of described first order surge protector for subsequent use and earth electrode electrical connection.
The utility model can also adopt following technical scheme:
Also comprise N level redundant electric surge protector unit, the second level to the, wherein N >=2, described N level redundant electric surge protector unit comprises N level surge protector for subsequent use and N level relay; One end of described N level relay coil is electrically connected with the end of incoming cables of N-1 level surge protector for subsequent use, and the other end is electrically connected with working zero line; Connecting after the normally-closed contact and fuse of described N level relay successively in the end of incoming cables of described N level surge protector for subsequent use, is electrically connected with the phase line of protective circuit; The leading-out terminal of described N level surge protector for subsequent use and earth electrode electrical connection.
Advantage and the good effect that the utlity model has are:
The utility model is by setting up surge protector redundant system, Surge Protector for subsequent use is connected to by relay on the circuit of main Surge Protector protection, under normal circumstances, back up between the end of incoming cables of Surge Protector and the circuit of protection in open-circuit condition, in the time of the fuse blows of the main Surge Protector series connection in work, main Surge Protector is ineffective, the normally-closed contact closure of the duplicate relay of first order redundant electric surge protector unit simultaneously, become normally off, in the circuit of protecting as the first order surge protector access for subsequent use of backup, continue to play the effect identical with main Surge Protector, the rest may be inferred, when prime surge protector for subsequent use lost efficacy because of the fuse blows of series connection with it, in the circuit of the surge protector access protection for subsequent use of rear class, thereby repeatedly discharging surge current, protect better power consumption equipment, and can repair in time the Surge Protector circuit of inefficacy.
