Description

Leakage detection equipment

technical field

The utility model relates to the technical field of leakage detection, in particular to a leakage detection device.

Background technique

In the existing municipal power supply system, leakage protectors are generally installed in each branch line and residential households. However, due to the aging of the lines or private pulling, leakage often occurs. The leakage protectors often trip and the leakage current The fault point cannot be eliminated in time and accurately, which directly affects the home appliances. For this reason, many households remove the leakage protector and replace it with a knife switch or an air switch. In this way, when the leakage current reaches a certain value, the leakage protector at the upper level will trip, and even the secondary main switch of the transformer will trip.

At present, there are two main types of leakage detection equipment put into use in the market: 1. Hand-held leakage detectors, which need to be hand-held on-site leakage testers to detect each part of the line, find possible leakage points, and then take certain measures; 2. The fault detection device is installed in the smart electric energy meter device installed on site, and the leakage fault record is sent through the communication system of the smart electric energy meter device.

For the hand-held leakage detector, the main disadvantages are: 1. It needs to be detected by the staff on site. After the fault occurs (after the protection switch), the on-site personnel cannot judge which level the fault occurred at. It needs to be powered on step by step to gradually detect the occurrence. At which level and which point is the source of the fault, the workload is huge and there is a risk of power consumption (recurrence of the original fault); 2. If the wiring is complicated on site, the risk of working safety of the staff will increase; 3. If there are multiple leakage locations , and leakage faults occur at different time periods and when different electrical appliances are working, fault judgment requires repeated detection, and sometimes multiple people may be required to detect at the same time, increasing labor costs; 4. Only manual recording of fault phenomena, locations, and times is easy to cause errors , can not automatically record the corresponding fault location and fault parameters. 5. It is impossible to capture the leakage current value when a fault occurs, and cannot provide a basis for fault prevention.

For the fault detection device installed in the smart energy meter device, the main disadvantages are: 1. The existing smart energy meter is not equipped with a data interface that can receive the response protection/detection of the leakage protection device. If the installation site needs to increase the leakage detection function The existing smart energy meters need to re-establish standards and replace them all; 2. Leakage faults are mainly aimed at suburban junctions, urban villages, areas where industrial power and residential power are cross-used, and the line is installed after the leakage fault is eliminated. It is not necessary to continue to use the leakage monitoring device after the leakage protection device, and replacing all the smart energy meters with the leakage monitoring function will cause huge capital and waste of manpower for engineering installation.

Utility model content

The technical problem to be solved by the utility model is to provide a leakage detection device, which can effectively monitor the leakage conveniently and at a relatively low cost.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical solution: a leakage detection device is provided, comprising:

An intelligent mobile terminal, which also includes a wireless master node module that establishes a wireless communication connection with the wireless slave node module of the leakage detection terminal to receive the leakage data of each node measured and uploaded by the leakage detection terminal and is connected to the wireless master node Module to obtain leakage data and display the intelligent display module.

Further, the wireless slave node module and the wireless master node module are GPRS wireless transmission modules.

Further, the leakage detection terminal is connected to each node to be tested in the power grid through the current clamp, and the leakage detection terminal is correspondingly provided with a connection interface docked with the current clamp.

Further, the leakage detection terminal further includes a data reading port connected to the leakage detection module.

After adopting the above technical scheme, the utility model has at least the following beneficial effects: the utility model can temporarily mount a leakage detection terminal at each leakage protection point of the existing three-level (or multi-level) power supply grid to monitor the node in real time. Leakage status, under the same station area, the leakage monitoring data of each node is wirelessly collected to the smart mobile terminal for centralized display at the same time point, which helps to accurately determine the location and size of the leakage, and quickly and effectively Troubleshoot to avoid recurring failures.

As shown in Figure 1, the utility model provides a leakage detection device, including:

Connected to the leakage detection terminal 1 at the node to be measured in the power grid, it also includes a leakage detection module 10 for detecting and saving leakage data at the node to be measured and is connected to the leakage detection module 10 to obtain leakage data and use The wireless slave node module 12 that is sent out in a wireless manner, when the leakage detection module 10 detects a leakage, will record and save the leakage current and the time of occurrence and send it to the wireless slave node module 12; and

Smart mobile terminal 2, which also includes a wireless master node module 20 that establishes a wireless communication connection with the wireless slave node module 12 of the leakage detection terminal 1 to receive the leakage data of each node measured and uploaded by the leakage detection terminal 1 and is connected to the The above-mentioned wireless master node module 20 is an intelligent display module 22 for obtaining leakage data and displaying it. The intelligent display module 22 can preferably adopt a high-resolution color touch-screen display, which has a good man-machine exchange interface and can intuitively display the current communication status and real-time event content.

In the application example shown in Figure 2, the leakage detection terminal 1 is connected to the leakage protection points of each level in the three-level power grid, specifically, connected to the corresponding electric meters A11, A12, A13... , A21, A22, A23..., A35, A36, A37... and so on.

Further, the leakage detection terminal 1 also includes a data reading port 16 connected to the leakage detection module 10, so that it is convenient to directly read leakage data from the leakage detection terminal 1 when necessary.

The main working process of the leakage detection device of the utility model is as follows: the leakage detection terminals 1 are respectively installed on the household electrical appliance lines that may leak electricity, and if leakage is detected on the line where it is located, the leakage current and time when it occurs will be formed into an event data packet in time, It is reported to the main node control module through wireless communication, and then forwarded to the intelligent display module 22 to display the current leakage event. Detectors can check the reported address of leakage detection terminal 1 to determine which line it is, and remove other leakage detection terminals 1 one by one to see if the current leakage event is still occurring and reported, and whether the reported leakage current value has changed. If it exists all the time, you can immediately determine the electrical leakage fault and the magnitude of the leakage current, so that you can quickly perform corresponding electrical processing and detection and protection work.
