Detailed Description
The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that variations and modifications can be made by persons skilled in the art without departing from the spirit of the invention. All falling within the scope of the present invention.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.
As shown in fig. 1, a circuit breaker management method provided in an embodiment of the present invention includes:
101, respectively obtaining model parameters and opening and closing times of each breaker in M breakers, wherein M is an integer larger than 1;
103, judging whether a target circuit breaker exists in the N first circuit breakers or not according to the opening and closing times, wherein the target circuit breaker is any two first circuit breakers of the N first circuit breakers, and the difference value of the corresponding opening and closing times is larger than a first threshold value;
and 104, if a target circuit breaker exists in the N first circuit breakers, generating first prompt information aiming at the target circuit breaker.
In this embodiment, the model parameter of the circuit breaker may refer to a specific model of the circuit breaker. In practical applications, each electrical device may be provided with circuit breakers with the same or different model parameters according to design requirements. The number of times of opening and closing of the circuit breaker can be the number of times of opening and closing experienced by the circuit breaker in practical application. In general, each circuit breaker or an accessory having a function of recording the number of times of opening and closing of the circuit breaker, such as a counter, can directly acquire the number of times of opening and closing of the circuit breaker through an electronic counter, and in the case of a mechanical counter, the number of times of opening and closing can be acquired through a visual system or based on a data entry operation of a user.
Since the selection of model parameters of circuit breakers of different electrical apparatuses is determined on the basis of their design parameters, circuit breakers of the same model parameters are generally used during the service life of the electrical apparatuses. In this embodiment, a plurality of circuit breakers whose application positions can be interchanged can be preliminarily determined by determining N first circuit breakers having the same model parameter from M circuit breakers, in other words, if the N first circuit breakers correspond to N electrical devices, in theory, any one of the N first circuit breakers may be suitable for controlling on/off of any one of the N electrical devices.
After the N first circuit breakers are determined, whether a target circuit breaker exists or not can be further determined, that is, whether two first circuit breakers of which the difference value of the opening and closing times is greater than a first threshold exist or not is determined, and if the target circuit breaker exists, first prompt information can be generated for the target circuit breaker. By combining with practical application, the first prompt information can be used for prompting that at least two circuit breakers which can be interchanged in application positions exist in a user, the opening and closing times of the circuit breakers have a large difference, and the user can interchange the application positions of two first circuit breakers in a target circuit breaker based on the first prompt information.
For example, there are a circuit breaker a and a circuit breaker B, which are respectively used for performing on-off control on an electrical device C and an electrical device D, and model parameters of the circuit breaker a and the circuit breaker B are the same, where the number of switching on and off times of the circuit breaker a is 300, and the number of switching on and off times of the circuit breaker B is 3000, which indicates that the on-off frequency of the electrical device C may be relatively low, and the on-off frequency of the electrical device D may be relatively high. Under the condition that the first threshold is 1000, the circuit breaker a and the circuit breaker B can be determined as a target circuit breaker, and first prompt information is generated for the target circuit breaker, on the basis, a user can interchange application positions of the circuit breaker a and the circuit breaker B according to the first prompt information, namely, the circuit breaker a is used for conducting on-off control on the electrical device D, and the circuit breaker B is used for controlling the electrical device C. Therefore, the switching-on and switching-off times of all the circuit breakers are relatively average, the situation that the circuit breakers of one part of electrical equipment are replaced for multiple times due to the fact that the service life of the switching-on and switching-off times of the circuit breakers of the other part of electrical equipment are far lower than the service life of the switching-on and switching-off times of the circuit breakers of the other part of electrical equipment is effectively avoided, and the requirement data of the circuit breakers are reduced.
According to the circuit breaker management method provided by the embodiment of the invention, N corresponding first circuit breakers with the same model parameters are determined from M circuit breakers, and when any two corresponding first circuit breakers with the opening and closing times difference larger than the first threshold exist in the N first circuit breakers, the first prompt information is generated, so that a user is prompted to perform application position exchange on the two circuit breakers with the larger opening and closing times difference, therefore, the opening and closing times of the corresponding circuit breakers are more average in the service life of each electrical device, the required number of the circuit breakers is reduced, and the acquisition cost of the circuit breakers is reduced. In addition, the opening and closing times of the circuit breaker are positively correlated with the metal fatigue and breakage degree of components such as a transmission connecting rod, a shaft pin and a spring in the circuit breaker, and the potential fault hazard caused by excessive opening and closing times of partial circuit breakers can be effectively avoided through the exchange of the application positions of the two circuit breakers with large opening and closing times difference.
Optionally, in step 104, if there is a target circuit breaker in the N first circuit breakers, generating first prompt information for the target circuit breaker includes:
if a target circuit breaker exists in the N first circuit breakers, respectively acquiring the operation time length of each first circuit breaker in the target circuit breaker;
respectively acquiring the opening and closing frequency of each first circuit breaker in the target circuit breaker according to the operation duration and the opening and closing times of each first circuit breaker in the target circuit breaker;
and under the condition that the difference value of the opening and closing frequencies of two first circuit breakers in the target circuit breaker is larger than a second threshold value, generating first prompt information aiming at the target circuit breaker.
In practice, the exchange of the application positions of the two circuit breakers is usually performed at regular intervals, for example during individual overhauls. For convenience of explanation, it is assumed in the following that the above application positions are exchanged at time t1, time t2, and time t 3. When a new circuit breaker a, which has failed to be replaced due to the electrical equipment C having a high frequency of start and stop, is started during the time t1 and the time t2, the number of times of opening and closing corresponding to the circuit breaker a may be relatively small. If the switching-on and switching-off times of the circuit breaker are only used as the basis for switching the application positions, at time t2, the application positions of the circuit breaker a and the circuit breaker B of the electrical device D with a low start-stop frequency are switched, which may further increase the difference between the switching-on and switching-off times of the circuit breaker a and the circuit breaker B at time t 3.
Therefore, in the embodiment, the switching-on and switching-off frequencies of the circuit breakers are calculated by combining the operation duration and the switching-on and switching-off times of the circuit breakers, and when the difference between the switching-on and switching-off times and the difference between the switching-on and switching-off frequencies of the two circuit breakers with the same type parameters meet the preset condition, the first prompt information is generated, so that the rationality of the first prompt information generation time is improved.
Optionally, in step 102, before determining N first circuit breakers from the M circuit breakers according to the model parameter, the method further includes:
respectively acquiring the service life of the opening and closing times of each circuit breaker in the M circuit breakers;
determining a frequency alarm threshold value of each circuit breaker according to the service life of the switching-on and switching-off frequency of each circuit breaker;
and under the condition that a second circuit breaker exists in the M circuit breakers, generating second prompt information aiming at the second circuit breaker, wherein the second circuit breaker is any circuit breaker of which the corresponding opening and closing times are greater than the corresponding time alarm threshold value.
In practical application, if the switch transmission mechanism of the circuit breaker is not completely disassembled and subjected to metal flaw detection, the hidden trouble that metal fatigue and fracture are caused by frequent operation in a transmission connecting rod, a shaft pin, a spring and the like in the circuit breaker is difficult to completely find. The potential metal fatigue and fracture fault hidden danger accumulated according to the overhaul experience is frequent on the switch transmission mechanism which reaches the service life of the switching-on and switching-off times.
According to the circuit breaker alarm method and the circuit breaker alarm device, the number of times of the circuit breaker is determined according to the number of times of opening and closing of the circuit breaker, the threshold value is alarmed, second prompt information is generated for the circuit breaker with the number of times of opening and closing larger than the number of times of alarming threshold value, and timely alarming is facilitated for the situation that faults and defects of the circuit breaker possibly occur.
Optionally, in step 102, the determining N first circuit breakers from the M circuit breakers according to the model parameter includes:
determining P third circuit breakers from the M circuit breakers, wherein the P third circuit breakers are all the circuit breakers except the second circuit breaker in the M circuit breakers;
determining N first breakers from the P third breakers.
In this embodiment, considering that the number of switching on and off times of some circuit breakers may be about to reach or reach the life time limit of the number of switching on and off times, the circuit breakers may be directly replaced without much value of replacing the application positions with other circuit breakers, so that the circuit breakers can be excluded from the circuit breakers for replacing the application positions, and unnecessary prompts for replacing the application positions of the circuit breakers are reduced.
The following describes a circuit breaker management method provided by an embodiment of the present invention with reference to an actual application scenario:
according to an equipment inventory and an electrical design drawing of a power plant, the using circuit breakers of all sections are checked by utilizing the opportunity of bus power failure maintenance, the corresponding consistency of the electrical equipment, the circuit breakers and the installation places of the electrical equipment is ensured, a switching-on and switching-off times statistical database is established according to a maintenance working section, and the information of the database mainly comprises 1) the names of the electrical equipment; 2 electrical device number (electrical device has double number or plant identification system (Kraftwerk-Kennzeichensystem, KKS) code); 3) rated current on the nameplate of the electrical equipment; 4) short circuit breaking current on the nameplate of the electrical equipment; 5) the delivery serial number (equivalent to the identification number) of the electrical equipment: 6) an electrical equipment installation site; 7) the date the electrical equipment was commissioned; 8) the opening and closing times of the circuit breaker; 9) and (5) remarking.
The circuit breaker management method provided by the embodiment of the invention is implemented by taking the manual acquisition and recording of the opening and closing times of the circuit breaker as an example:
in the prior art, the overhaul of the circuit breaker is performed according to 10KV of a plant system of 6.4 plant system and the following overhaul of the circuit breaker (which is formulated according to DL/T593 and a switch delivery specification) in term of DL/T838 and 2017 "overhaul guide of coal-fired thermal power generation enterprise equipment", which specifies ten overhaul items of a vacuum circuit breaker, refer to standard items of the vacuum circuit breaker, and specifically as shown in fig. 2, the overhaul items include:
1. checking the outside of the breaker body, and cleaning the porcelain bushing;
2. inspecting the appearance of the vacuum bubble;
3. checking a connecting rod and a shaft pin of the transmission part, and oiling and realizing fastening;
4. cleaning and checking an insulator, namely an insulating cylinder shell, and fastening a wiring terminal by using a bolt;
5. checking and cleaning each element of the electric control loop, and fastening screws;
6. carrying out five-prevention transmission and adjusting test;
7. checking a connecting rod and a shaft pin of a transmission part, oiling and fastening a bolt;
8. checking a damp-proof heating device;
9. testing the mechanical characteristics of the switch;
10. electric test
In the items listed in fig. 2, the statistics and the inspection of the switching-on and switching-off times of the switch are not carried out, and if the switch transmission mechanism is not completely disassembled and subjected to metal flaw detection, the hidden trouble that metal fatigue and fracture are caused by frequent operation in the transmission connecting rod, the shaft pin, the spring and the like cannot be completely found. This potential metal fatigue and breakage potential is a frequent accumulation based on maintenance experience on switches that are reaching design life quickly. Therefore, statistics and data entry of the opening and closing times are added in a standard maintenance procedure when the maintenance opportunity (interval period is about 2 years) of the unit above the B level is utilized, and the exchange of 'more' and 'less' of the opening and closing times of the circuit breakers of the same type is carried out based on the implementation of the circuit breaker management method in the embodiment. Specifically, the optimized overhaul flow chart is shown in fig. 3. Compared with fig. 2, statistics on the opening and closing times of the circuit breaker is added between steps 1 and 2 in fig. 2, and the opening and closing information ledger is added (i.e. recorded into the database); and a combined switching-on and switching-off times counting machine account is added after step 10 of fig. 2, and the same type of switches are compared to perform the switching of more and less (namely, the switching-on and switching-off times of the same type of circuit breakers are exchanged between more and less based on the circuit breaker management method).
Carry out the back of exchanging of the same section with model separating brake number of times "many" and "few" switch to the switch, must carry out the change that corresponds to the data plate on the circuit breaker body, ensure to keep unanimous with the cubical switchboard body name of change, prevent to take place because of the maloperation accident that the data plate mistake leads to. Meanwhile, the switching-on time counting machine account and the equipment machine account can be updated in time after the replacement is finished, and the effective correspondence between the maintenance record and the equipment is ensured.
The process is only used for supplementing and optimizing standard items, the maintenance link is simple, all parameters of the circuit breaker to be exchanged are guaranteed to be consistent, implementation is convenient, and the effect is obvious. After the implementation of the process, the aging speed of the frequently started circuit breaker can be obviously reduced, the equipment reliability is greatly improved, and the direct or indirect economic loss caused by the fault of the circuit breaker is avoided; meanwhile, the occurrence rate of faults and defects of the vacuum circuit breaker which is frequently started can be effectively reduced, the exposure time of personnel in dangerous operation is reduced, and the safety risk of the operation is reduced.
