According to the plastic case circuit breaker fault prompting and positioning control system, the fuse, the fault auxiliary contact and the audible and visual alarm are arranged, and the line inlet side L1 phase of the plastic case circuit breaker is selected as the control power supply of the positioning control system, when the plastic case circuit breaker breaks down, the fault auxiliary contact acts on and is closed, the power supply of the audible and visual alarm is switched on to give out alarm sound and flash, and if the current exceeds a specified value, the fuse is switched off to protect the audible and visual alarm, so that field maintenance personnel can accurately and efficiently position the faulty plastic case circuit breaker, and the positioning control system is convenient to install, simple to maintain and low in cost.
Description
Technical Field
The utility model relates to a molded case circuit breaker, in particular to a fault prompting, positioning and controlling system of the molded case circuit breaker.
Background
In the prior art, when a molded case circuit breaker in a low-voltage switch cabinet breaks down, the broken molded case circuit breaker trips, 1 fault signal is transmitted to a background control center, and then the background control center immediately sends a maintainer to process the fault of the molded case circuit breaker on site.
However, a new problem occurs when a service man goes to find and determine the orientation of the faulty molded case circuit breaker on site: a molded case circuit breaker having a fault cannot be accurately and efficiently located.
Because a plurality of low-voltage switch cabinets in the power distribution room have the same appearance and the same color, when the molded case circuit breaker is required to be searched, the cabinet number must be searched first, and the loop number of the molded case circuit breaker is searched after the cabinet number is determined; meanwhile, the cabinet number and the loop number are formed by a string of numbers and letters, so that the plastic case circuit breaker is not intuitive and is easy to be confused and mistaken, the positioning of the plastic case circuit breaker is easy to make mistakes or valuable maintenance time is delayed, and serious economic loss or personnel injury can be caused.
For example, 11.2019, 11.11.11, a certain online shopping company in China holds a large online shopping activity, and when the netizens are just in prosperous online shopping, one way of molded case circuit breaker of the low-voltage power distribution room of the data center in the place of Shenzhen suddenly breaks down and trips, so that a server is powered off and stops running.
The control center sends a maintainer to a field for processing immediately after obtaining a fault signal at the first time, and it is not thought that the maintainer does not find a fault molded case circuit breaker in 5 minutes, so that the loss of a certain online shopping company is about 1 hundred million, and the data center is penalized by 200 ten thousand major accidents.
Therefore, further improvements are needed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a fault prompting and positioning control system for a molded case circuit breaker, which has the advantages of simple structure, convenience in installation, simplicity in maintenance, low cost and strong practicability, so that the problem that the fault molded case circuit breaker cannot be accurately and efficiently positioned is effectively solved, and the defects in the prior art are overcome.
A moulded case circuit breaker fault suggestion positioning control system who designs according to this purpose, its characterized in that: the circuit breaker comprises a molded case circuit breaker, a fuse, a fault auxiliary contact, an audible and visual alarm and a control power supply, wherein the control power supply is respectively connected with the fuse and the fuse, the fault auxiliary contact and the audible and visual alarm are sequentially connected.
The control power supply is an L1 phase at the wire inlet side of the molded case circuit breaker, and the audible and visual alarm is connected with an N phase at the wire outlet side.
The molded case circuit breaker is equipment for protecting and distributing electric energy, and can automatically trip to disconnect a power line and send a fault signal when power utilization fails.
The fault auxiliary contact is an internal accessory of the molded case circuit breaker, and has three contacts: the circuit breaker is characterized by comprising a common point, a normally-open point and a normally-closed point, wherein the fuse is connected with the normally-open point, when the molded case circuit breaker breaks down, a fault auxiliary contact of the molded case circuit breaker acts simultaneously, and the normally-open point closes after acting; disconnecting after the normally closed point acts; the common point is the function of the coupling.
The fuse is an element for protecting the secondary circuit, and when the current exceeds a predetermined value for a certain period of time, the fuse melts by heat generated by the fuse itself, thereby breaking the circuit.
The audible and visual alarm is an alarm signal device which sends out alarm signals to the outside through sound and various lights.
The utility model adopts the molded case circuit breaker, the fault auxiliary contact, the fuse and the audible and visual alarm, and forms an accurate and efficient molded case circuit breaker fault prompting and positioning control system through reasonable and effective combination.
When the molded case circuit breaker breaks down, the fault auxiliary contact acts to be closed, the power supply of the audible and visual alarm is connected to enable the audible and visual alarm to give out alarm sound and flash, and if the current exceeds a specified value, the fuse is disconnected to protect the audible and visual alarm, so that field maintenance personnel can accurately and efficiently position the broken molded case circuit breaker, and the positioning control system is convenient to install, simple to maintain and low in cost.
Drawings
Fig. 1 is a schematic circuit diagram of a positioning control system according to an embodiment of the present invention.
Detailed Description
The utility model is further described with reference to the following figures and examples.
Referring to fig. 1, the plastic case breaker fault prompting, positioning and controlling system is applied to a low-voltage switch cabinet and comprises a plastic case breaker 1, a fuse 2, a fault auxiliary contact 3, an audible and visual alarm 4 and a control power supply, wherein the control power supply is taken from an incoming line side L1 phase of the QF plastic case breaker 1, then the control power supply is respectively connected with the QF plastic case breaker 1 and an FU fuse 2, and then a normally-open point of the SDE fault auxiliary contact 3 is connected with the HL audible and visual alarm 4, and finally an N phase of an outgoing line side is connected, so that a complete loop is formed.
The fault auxiliary contact 3 is provided with a common point, a normally-open point and a normally-closed point, and the fuse 2 is connected with the normally-open point of the fault auxiliary contact 3.
When the molded case circuit breaker 1 breaks down, the fault auxiliary contact 3 acts and closes, and the power supply of the audible and visual alarm 4 is switched on to make the molded case circuit breaker emit alarm sound and flash light, so that when a maintainer comes to the site, the position of the cabinet can be judged by sound, the sound transmission cannot be influenced even if the cabinet blocks a lot of sight lines, and the inspiration is the same as that when an automobile makes a sharp turn in a mountain by pressing a horn; whether the cabinet numbers are consistent or not is confirmed after the cabinet is positioned, the molded case circuit breaker 1 is positioned in the loop in the right state through flashing, and whether the loop labels are consistent or not is checked, so that the molded case circuit breaker 1 with faults can be accurately and efficiently positioned.
The foregoing is a preferred embodiment of the present invention, and the basic principles, principal features and advantages of the utility model are shown and described. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are intended to illustrate the principles of the utility model, but that various changes and modifications may be made without departing from the spirit and scope of the utility model, and the utility model is intended to be protected by the following claims.
