Abstract
The invention discloses an online monitoring unit of a temperature signal for a transformer substation, which comprises a temperature collecting unit, a temperature receiving unit and a computer processing unit connected sequentially. The temperature collecting unit comprises a temperature sensor and a signal emitter. The temperature sensor is arranged at a bus connecting part and connected with the signal emitter through a signal line. The signal emitter is connected with the temperature receiving unit and the temperature sensor is obviously separated from the signal emitter. The online monitoring unit of the temperature signal for the transformer substation provided by the invention separates the temperature sensor from the signal emitter with a simple structure and low cost, improves temperatures of the temperature sensor and the signal emitter at different time points, ensures the normal operation of the signal emitter, and further reduces the failure rate of the system so as to achieve high reliability.
Description
Technical field
The present invention relates to the electrical substation monitoring equipment technical field, relate in particular to a kind of transformer station with temperature signal on-line monitoring unit.
Background technology
The integrated epoxide resin material of thermometric of substation bus bar connecting portion heating temperature-sensitive unit is easily under the situation of electric load increase, existing equipment loose contact; Be rapidly heated; The normal range that surpasses monitor current and temperature very soon; Easily epoxide resin material is made a mess of, the wireless temperature transmitter unit will be made a mess of.And then influence the normal operation of transformer station, bring potential safety hazard to transformer station easily.
Summary of the invention
The purpose of this invention is to provide a kind of good reliability, high safety, the easy transformer station of replacing with temperature signal on-line monitoring unit.
A kind of transformer station is with temperature signal on-line monitoring unit; Comprise the temperature collecting cell, temperature receiving element and the computer processing unit that connect successively; Temperature collecting cell comprises temperature sensor and signal projector, and said temperature sensor is arranged on the bus connecting portion, and it is connected with signal projector through signal wire; Said signal projector is connected with temperature receiving element signal, and said temperature sensor and signal projector are obviously isolated.
It is arranged on said temperature sensor outside the launch site of signal projector.
Transformer station of the present invention with temperature signal on-line monitoring unit with its simple structure; Cheap cost has realized separating of temperature sensor and signal projector; Realized that temperature sensor and signal projector do not improve temperature simultaneously; Ensured the normal operation of signal projector, system failure rate further reduces, and reliability is high.
Description of drawings
Below in conjunction with accompanying drawing the present invention is done further explanation:
Fig. 1 is a structural representation of the present invention.
Embodiment
Like Fig. 1; A kind of transformer station comprises the temperature collecting cell 1, temperature receiving element 2 and the computer processing unit 3 that connect successively with temperature signal on-line monitoring unit, and temperature collecting cell 1 comprises temperature sensor 4 and signal projector 5; Said temperature sensor 4 is arranged on bus connecting portion 6; It is connected with signal projector 5 through signal wire 7, and said signal projector 5 is connected with temperature receiving element 2 signals, and said temperature sensor 4 is obviously isolated with signal projector 5.Said temperature sensor 4 is arranged on outside the launch site of signal projector 5.This unit is with its simple structure; Cheap cost has realized separating of temperature sensor and signal projector, has realized that temperature sensor and signal projector do not improve temperature simultaneously, have ensured the normal operation of signal projector; System failure rate further reduces low, and reliability is high.
