Abstract
The utility model discloses a fixing part of a monitoring sensor of vibration signals of a circuit breaker. The fixing part comprises a sensor probe base and is characterized by further comprising a recessed magnet separation sleeve connected with the bottom face of the probe base and a permanent magnet seat located in the magnet separation sleeve. Screw holes are arranged on the bottom face of the probe base, central holes are arranged in the middle of the recessed magnet separation sleeve and the permanent magnet seat, and the two center holes are fixedly connected with the screw holes on the bottom face of the probe base through screws in screw mode. Due to the fact that the recessed magnet separation sleeve and the permanent magnet seat are fixedly connected onto the bottom face of the sensor probe base, and the bottom face of the permanent magnet seat can be stably absorbed on the circuit breaker or a steel piece on the periphery of the circuit breaker by means of strong magnetic force, drilling installation is not required in design of the circuit breaker, and adhesive connection which is convenient to operate and not stable is not required. The fixing part is convenient to install, ensures long-term stable work under vibration work conditions, and is suitable for installation of various monitoring sensors of the vibration signals of the circuit breaker.
Description
Technical field
The utility model relates to a kind of device, especially fixed part of Circuit breaker vibration signal monitoring sensor of mechanical oscillation signal monitoring immobilising device.
Background technology
Circuit breaker is a kind of not only can the connection and disjunction normal duty electric current and overload electric current, can also connect the device for switching with the disjunction short circuit current.Circuit breaker except playing control action, also has certain defencive function in circuit, such as overload, short circuit, under-voltage and earth leakage protective etc.Along with the raising of the intelligent degree of electric power system and reliability requirement, in the urgent need to the High Voltage Circuit Breaker Condition is carried out Real-Time Monitoring, forecast, and be supplying method and the decision-making of fixing a breakdown.To the monitoring of circuit breaker vibration important part wherein, the monitoring of existing circuit breaker vibration comprises setting and the installation of circuit breaker vibrating sensor, by being installed in the other transducer of circuit breaker, obtain the circuit breaker vibration information, then this information is processed and analyzed, can obtain correlation behavior and the monitoring of circuit breaker operation.In the prior art of Circuit breaker vibration signal monitoring, relevant technical products must just set the structure that the Circuit breaker vibration signal monitoring sensor is installed in punching at the beginning of circuit breaker design, the corresponding installation of transducer of having chosen got final product.And can't put into operation or at the beginning of design in the breaker apparatus that arranges fixedly mount transducer, perhaps use the method sensor installation of pasting, this installation is inconvenient, more can't guarantee stable for extended periods of time work under operating mode is vibrated.
The utility model content
The purpose of this utility model provides a kind of easy for installation, guarantees the Circuit breaker vibration signal monitoring sensor fixed part of stable for extended periods of time work under the operating mode vibration.
For reaching above-mentioned purpose, the technical solution of the utility model is:
A kind of Circuit breaker vibration signal monitoring sensor fixed part, it comprises the sensor probe base, characterized by further comprising:
The spill magnetic shield that is connected with described probe mount bottom surface and permanent magnet seat wherein.
Described probe mount bottom surface is provided with screw, and the centre of spill magnetic shield and permanent magnet seat is provided with centre bore, is threaded fixing by screw with the screw of probe mount bottom surface in two centre bores.
Centre bore on the described permanent magnet seat lateral surface is counterbore, and head of screw is sunk wherein fully.
The Circuit breaker vibration signal monitoring sensor fixed part of above structure, at sensor probe base end face be fixedly connected spill magnetic shield and permanent magnet seat thereof, and its powerful magnetic force can be passed through in the bottom surface of permanent magnet seat, stably be adsorbed on the steel and iron parts on circuit breaker or its periphery, punching need to just be set when circuit breaker design install, or be connected with being inconvenient to operate with unsteady viscose glue.Easy for installation, guarantee stable for extended periods of time work under the operating mode vibration.Also have the following advantages:
1. coaxial type structure, compact conformation is applicable to the narrow space in the circuit breaker mechanism case;
2. the high-intensity magnetic field that produces when magnetic shield protection magnet magnetic force is not subjected to the circuit breaker drop-out current affects, and avoids interference simultaneously to close on electromagnetic type relay adhesive action in the circuit breaker mechanism case;
3. the outside of deivce face can not adsorb secondary connection nose metalloid foreign matter after magnetic shield was guaranteed the monitoring sensor installation.
Description of drawings
Fig. 1 is stereo decomposing structural representation of the present utility model.
Fig. 2 is sectional structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Shown in Figure 1, be decomposition texture schematic diagram of the present utility model.As we know from the figure, the utility model comprises probe mount 1, spill magnetic shield 2, permanent magnet seat 3 and screw 4.Sectional structure schematic diagram in conjunction with Fig. 2 comes together to see that a termination of probe mount 1 is provided with screw thread 5, is used for the fixation of sensor probe; The outside of another termination is turret head 7, and available corresponding wrench fastening position or rotation probe mount 1 are popped one's head in sensor installation; In the middle of the end face of probe mount 1 hexagon one end, be provided with screw 6.The centre of spill magnetic shield 2 and permanent magnet seat 3 is provided with centre bore 8, permanent magnet seat 3 is enclosed within the spill magnetic shield 2, screw 4 one ends pass this centre bore 8 and are threaded with the screw 6 of probe mount 1, tighten spill magnetic shield 2 is fixedly connected with probe mount 1 with permanent magnet seat 3, consist of Circuit breaker vibration signal monitoring sensor fixed part of the present utility model.Centre bore 8 on permanent magnet seat 3 lateral surfaces is counterbore, and the head of screw 4 is sunk wherein fully, and the bottom surface that being set to of this counterbore guarantees permanent magnet seat 3 is a plane with extraneous joint face, realizes firmly connecting.
The spill magnetic shield 2 of reporting and permanent magnet seat 3 are prior art products, or the person skilled in art can make easily according to prior art and needs.
