Abstract
The utility model discloses a temperature signal online monitoring unit for a transformer substation. The temperature signal online monitoring unit comprises a temperature acquisition unit, a temperature receiving unit and a computer processing unit, wherein the temperature acquisition unit, the temperature receiving unit and the computer processing unit are connected in sequence; the temperature acquisition unit comprises a temperature sensor and a signal emitter; the temperature sensor is arranged on a bus connecting part and is connected with the signal emitter through a signal line; the signal emitter is connected with the temperature receiving unit by means of a signal; and the temperature sensor and the signal emitter are obviously isolated. Due to the simple structure and low cost of the temperature signal online monitoring unit, the temperature sensor and the signal emitter are separated, the temperatures of the temperature sensor and the signal emitter are not increased at the same time, the normal operation of the signal emitter is ensured, the failure rate of a system is further reduced, and the reliability is high.
Description
Technical field
The utility model relates to the electrical substation monitoring equipment technical field, relates 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.
The utility model content
The purpose of the utility model provides 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.
The utility model transformer station 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 utility model is done further explanation:
Fig. 1 is the structural representation of the utility model.
Embodiment
