Description
Technical field
The invention belongs to SPD intelligent monitor system technical fields, concretely relate to a kind of DPS intelligent terminal's unit.
Background technology
SPD is widely used in protecting lightning surge, and due to the aging or normal aging that is struck by lightning, SPD should automatically disengage power distribution system
When system, although built-in aging thermal release devices of SPD, and end is mounted with back-up protection device thereon, but SPD are aging, heat is de-
Button, back-up protection are failed and cause the phenomenon of the overheated burnings of SPD to happen occasionally.SPD ageing failures are dynamic changing processes, and which is right
Ground leakage micro-current can progressively become big with aging aggravation, so that last fail, temperature of the existing SPD on-line monitorings only to SPD
It is monitored, not the leakage micro-current on-line real time monitoring to SPD, at all cannot On-Line Dynamic Monitoring SPD ageing failures, it is impossible to
Meet unattended requirement.
The content of the invention
It is an object of the invention to provide a kind of SPD intelligent terminal's unit, in fact now On-Line Dynamic Monitoring SPD ageing failures,
Meet unattended use needs.
To solve above-mentioned technical problem, the object of the present invention is achieved like this：
A kind of SPD intelligent terminal's unit, including core processor, core processor are de- with back-up protection monitoring means, heat respectively
Button monitoring means, temperature monitoring unit, number of lightning strokes monitoring means, telecommunication unit are connected；Core processor also with it is micro-
Current monitoring unit is connected, and, by micro-current transformer, the secondary side of micro-current transformer is believed for earth lead or phase line connecting line
Number it is connected with micro-current monitoring means ,+12V, -12V that the power end of micro-current transformer is provided with micro-current monitoring means
DC source connects, and RS485 buses or ethernet interface are included on telecommunication unit, and realization is communicated with host computer.
On the basis of such scheme and as the preferred version of such scheme：4 tunnel back-up protection states are input into and standby
Monitoring for protection unit is connected；4 road SPD are warm, and trip status input is connected with hot dropout monitoring means；1 road PT100 temperature is defeated
Enter and be connected with temperature monitoring unit；The secondary side signal input of 1 road lightening inductor is connected with number of lightning strokes monitoring means.
The present invention is prominent and beneficial compared to existing technology to be had the technical effect that：
SPD intelligent terminal's unit of the present invention, it is single by hot dropout monitoring means, back-up protection monitoring means, micro-current monitoring
Unit realizes On-Line Dynamic Monitoring SPD aging performances, by core processor and telecommunication unit be connected realize SPD nobody
Use requirement on duty.

Device 8, the secondary side of micro-current transformer 8 are connected with micro-current monitoring means, micro-current monitoring means export 1 tunnel+12V, 1
Road -12V DC sources, the power end of micro-current transformer 8 are respectively connected to+12V DC sources, -12V power supply DC sources, micro-
Current transformer collection SPD leakage micro-current signals, realize the on-line monitoring of SPD ageing states.
RS485 buses or ethernet interface are included on telecommunication unit, realization is communicated with host computer.Realize
SPD unmanneds.
L1, L2, L3, N running status of the back-up protection of SPD accesses back-up protection state output terminal mouth, 4 tunnel back-up protections
State input is connected with back-up protection monitoring means；Realize that SPD backup status are monitored on-line.
The hot trip status in 4 tunnels of SPD access hot trip status input port, the hot trip status inputs of 4 road SPD and heat dropout
Monitoring means are connected；Realize the hot trip status on-line monitorings of SPD.
1 road PT100 temperature input is connected with temperature monitoring unit, realizes the online of SPD surface temperatures or spin manifold temperature
Monitoring.
1 road lightening inductor secondary side signal input is connected with number of lightning strokes monitoring means；Realize thunderbolt situation
Line is monitored.
Above-described embodiment is only presently preferred embodiments of the present invention, is not limited the scope of the invention according to this, therefore：It is all according to
The equivalence changes done by the structure of the present invention, shape, principle, all should be covered by within protection scope of the present invention.
