Abstract

The utility model discloses a 100 to 250A redundant current fire-disaster alarming device, which mainly comprises an outer shell, a panel, a display screen, a speaker, an arc chute, an input terminal, an output terminal, a control terminal block, a telecommunication network terminal, a zero sequence transformer, a segregated phase current transformer, a breaker, a transformer and an electric control board. The zero sequence transformer, the segregated phase current transformer, the breaker, the transformer and the electric control board are arranged inside the outer shell. The zero sequence transformer is arranged at a side of an input of the breaker and the segregated phase current transformer is arranged at the side of the output; a side of the breaker is provided with the transformer, the other side of the transformer is provided with the electric control board which is provided with the control terminal block and telecommunication network terminal. The utility model has the advantages of high sensitive degree of structure, strong reliability, compact structure, small size, simple installing and operation, and long period of usage. The utility model has the functions: on-site conservation for fire accident, alarming and black box, detecting residual current of the system, and long-range communication with a host through bus.

Description

100～250A residual current fire alarm installation

Technical field: the utility model relates to a kind of low-voltage electrical apparatus, especially a kind of residual current fire alarm installation.

Background technology: traditional earth leakage protective device, most of during protection circuit by the thermo magnetic trip release action, changed by environment temperature and change, cause protection value precision inaccurate.And function singleness, generally only have excess current, short circuit, creepage protection function.In case during action, will have a power failure for a long time, influence the normal electricity consumption of user.And can't carry out the partition of data remote and data, and fault type is unclear, can not the record queries fault, and various important parameters can't show, can not satisfy different occasion needs.

Summary of the invention: at above-mentioned the deficiencies in the prior art, the utility model provides a kind of function residual current fire alarm installation many, simple in structure.

For achieving the above object, the technical solution adopted in the utility model is: 100～250A residual current fire alarm installation mainly comprises shell (3), panel (1), display screen (2), loudspeaker (6), flash barrier (5), input terminal (4), outlet terminal (11), control connection terminal (7), network service terminal (8), zero-sequence transformer (9), divide phase current mutual inductor (10), isolating switch (12), transformer (13), Electronic Control plate (14).Panel (1) is fixed on the front end of shell (3).Display screen (2) is on the panel (1).Loudspeaker (6) are in the side of shell (3).Input terminal (4) and outlet terminal (11) are fixed on the shell (3), are in the two ends up and down of panel (1) respectively.Flash barrier (5) is on input terminal (4) and the outlet terminal (11).Zero-sequence transformer (9) is divided phase current mutual inductor (10), isolating switch (12), and transformer (13), Electronic Control plate (14) is in the shell (3).The distolateral zero-sequence transformer (9) of joining of isolating switch (1 2) inlet wire, the distolateral partition phase current mutual inductor of outlet (10), the side distribution transforming depressor (13) of isolating switch (12), the sub-control panel of opposite side distribution (14) of transformer (13) has control connection terminal (7) and network service terminal (8) on the Electronic Control plate (14).

The utility model is highly sensitive, good reliability, compact conformation, little, the installation, simple to operate of volume, long service life.Have fire and protect on the spot, report to the police and black box function, but and the residual current of detection system, can be by bus and main frame implementation telecommunication.
