Abstract
The utility model discloses a vacuum degree online monitoring system, comprising a vacuum degree online monitoring device, sensor units and a reset unit. The vacuum degree online monitoring device is integrated by a signal processing unit and a control unit, and the vacuum degree online monitoring device is mounted inside an operation panel of a circuit breaker; the sensor units are mounted on an outer shell of the circuit breaker directly facing each phase vacuum arc extinguish chamber, and the sensor units are connected with the vacuum degree online monitoring device through high-frequency coils; and a power supply, alarm signals and reset signals of the vacuum degree online monitoring device are directly connected to an aviation plug of the circuit breaker, and are led to a secondary small chamber of the circuit breaker through the aviation plug.
Description
Technical field
The utility model relates to the vacuum degree on-line monitoring system, belongs to electrical technology field.
Background technology
Vacuum circuit-breaker is one of power domain equipment the most commonly used, and its reliability directly influences safe operation and the reliability of electric power system.And what influence the vacuum circuit-breaker reliability mainly is the indoor vacuum degree of vacuum circuit-breaker vacuum extinction.
At present, Chang Yong breaker vacuum degree measurement is divided into two kinds of off-line monitoring and on-line monitorings.Off-line monitoring need have a power failure to equipment, often because move reason, can not reflect the ruuning situation of circuit breaker timely.Had the on-line monitoring equipment of breaker vacuum degree in recent years, but its work is not very stable, and lead-in wire is complicated, when pulling out circuit breaker, need disconnect pickup wire, otherwise can in the process of pulling out, pickup wire be pulled apart because pin problem cause some other reach aesthetic problem safely and be not easy to allow the user accept.Therefore, to designing a kind of new vacuum degree on-line monitoring system, allow users accept, seeming is even more important, and the on-line monitoring industry is also had important meaning.
Summary of the invention
The utility model provides a kind of vacuum degree on-line monitoring system in order to solve deficiency of the prior art, improves original mode of connection, and itself and breaker body are combined together, improves device operational reliability and stability.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of vacuum degree on-line monitoring system, comprise vacuum degree on-Line Monitor Device, sensor unit, reset unit, described vacuum degree on-Line Monitor Device is become one by signal processing unit and control unit, the vacuum degree on-Line Monitor Device is installed on the guidance panel inside of circuit breaker, merge with vacuum circuit-breaker is perfect, externally can't see this on-Line Monitor Device, make device more attractive in appearance.
Sensor unit is installed on the case for circuit breaker that every phase vacuum interrupter faces, and sensor unit directly links to each other with the vacuum degree on-Line Monitor Device by high-frequency line, and the short and middle non junction of lead-in wire transmits more favourablely to signal, can improve operational reliability.
The power supply of vacuum degree on-Line Monitor Device, alarm signal, slot signal directly are connected to the aviation plug of circuit breaker, cause in the circuit breaker secondary cell by aviation plug, thereby when drawing circuit breaker, pull out aviation plug, pull out circuit breaker, the vacuum degree on-Line Monitor Device is also together pulled out, and does not need to pull out sensor terminal again, pull out circuit breaker again, make operation more simple and reliable.
Beneficial effect:
Vacuum degree on-line monitoring system involved in the present invention, attractive in appearance, the integrity problem of original mounting means have not only been solved, also reduced the quantity of instrument indoor equipment, reduced the installation work amount, simplified secondary connection, made that operating maintenance personnel's operation is more simple, reduced the misoperation probability, improved system reliability, and saved maintenance workload and maintenance cost, this is to operation of power networks and realize that the equipment refinement management all has very important significance.
Description of drawings
Fig. 1 is vacuum degree on-line monitoring system schematic diagram of the present invention described in the utility model;
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Embodiment 1
As shown in Figure 1, described in the utility modelly the utility model discloses a kind of vacuum degree on-line monitoring system, comprise vacuum degree on-Line Monitor Device, sensor unit, reset unit, described vacuum degree on-Line Monitor Device is become one by signal processing unit and control unit, and the vacuum degree on-Line Monitor Device is installed on the guidance panel inside of circuit breaker; Sensor unit is installed on the case for circuit breaker that every phase vacuum interrupter faces, and sensor unit directly links to each other with the vacuum degree on-Line Monitor Device by high-frequency line; The power supply of vacuum degree on-Line Monitor Device, alarm signal, slot signal directly are connected to the aviation plug of circuit breaker, cause in the circuit breaker secondary cell by aviation plug.
Though in the specification execution mode of the present utility model is illustrated, these execution modes just as prompting, should not limit protection range of the present utility model.Carrying out various omissions, displacement and change in the scope that does not break away from the utility model aim all should be included in the protection range of the present utility model.
