Abstract

The utility model relates to a transformer substation bus phase voltage off-limit alarm system. The system comprises a master station and a plurality of station ends, the station ends and the master station are connected through network channels or serial port channels, the master station is connected with the plurality of station ends simultaneously, each station end comprises a station end measurement and control device and a remote terminal unit (RTU), the station end measurement and control device is connected with primary equipment mounted on the bus through a circuit and acquires data from the primary equipment, and the station end measurement and control device is connected with the remote terminal unit (RTU) through the circuit; and the master station comprises a dispatching master station prepositive server, a real-time server, a SCADA human-computer interface and a voice alarm device. The system that a detection method of the utility model uses is simple in structure, relatively low in equipment cost, and is easy to carry and realize, detection and judgment are accurate, interference and influence of branch circuits are prevented, and labor is saved, thereby greatly shortening fault maintenance time, reducing loss of electrical equipment, and improving safety of the electrical equipment.

Description

Substation bus bar phase voltage off-limit alarm system
Technical field
The utility model belongs to electric power O&M technical field, especially a kind of substation bus bar phase voltage off-limit alarm system.
Background technology
At present, the small current neutral grounding device alarm function in transformer station is unstable, when circuit generation earth fault, sometimes there is no the ground connection alarm signal, cause the regulation and control personnel to be difficult to find in time line-to-ground fault, power network safety operation is caused a hidden trouble, good service is caused to harmful effect.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides lower, the easy lift-launch of a kind of equipment cost to realize, detect accuracy of judgement, the substation bus bar phase voltage off-limit alarm system timely of reporting to the police.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of substation bus bar phase voltage off-limit alarm system, comprise main website and a plurality of stations end, stand the end with main website between by network channel or serial ports passage, be connected, main website connects a plurality of stations end simultaneously, it is characterized in that:
The end of standing comprising station end measure and control device and remote terminal unit equipment (RTU), and the end measure and control device of stand is arranged on primary equipment on bus by connection and, from this primary equipment image data, stand and hold measure and control device to pass through connection remote terminal unit equipment (RTU);
Main website comprises scheduling station front server, real-time server, SCADA man-machine interface and voice alarming device, the scheduling station front server connects real-time server by data line, real-time server is by connection SCADA man-machine interface, and this SCADA man-machine interface shows the data that real-time server obtains and the data to server inside are arranged by the SCADA man-machine interface.
And described SCADA man-machine interface is implanted into the whole network regulation and control figure, monitor each substation bus bar voltage more clear and intuitively, for out-of-limit value, according to color relation, can finely distinguish.
And described SCADA man-machine interface also is connected with voice alarming device, when the out-of-limit warning of sounding of bus phase voltage data.
Advantage of the present utility model and good effect are:
The system architecture that detection method of the present utility model is used is simple, lower, the easy lift-launch of equipment cost realizes, and detection accuracy of judgement, avoid the disturbing effects such as branched line, and save artificial, thereby greatly shorten corrective maintenance time, reduce the loss loss of power equipment, promote power equipment safety.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of substation bus bar phase voltage off-limit alarm system, comprise main website and a plurality of stations end, stand the end with main website between by network channel or serial ports passage, be connected, main website connects a plurality of stations end simultaneously;
