Description
Technical field
The utility model relates to a kind of monitor, be specifically related to a kind of electrical leakage, discharge monitor for lightning arrester.
Background technology
Lightning arrester protects power equipment from the important electrical of overvoltage injury in electrical network, and its reliability of operation will directly affect the safety of electric system.In the past, to the monitoring of lightning arrester by artificial every day or make an inspection tour weekly reometer and carry out, cannot Timeliness coverage fault, be more difficult to the larger defect finding to produce fault.Degradation faster lightning arrester is completely likely just blasted within a tour cycle, and the repeatedly similar explosion accident occurred in recent years, not only bring huge economic loss, and serious threat is to the safe operation of electrical network.
Therefore, need a kind of equipment that can detect lightning arrester, detect its electric discharge electric leakage situation at any time.
Utility model content
For the deficiency that prior art exists, the utility model object is to provide a kind of electrical leakage, discharge monitor for lightning arrester, and structure is simple, easy to use and reliable, can effectively detect lightning arrester inherent vice, find fault at any time, avoid Explosion of on Arrester, reduce accident rate.
To achieve these goals, the utility model realizes by the following technical solutions: electrical leakage, discharge monitor for lightning arrester, comprise stainless steel casing, power supply communication pilot lamp, LCDs, insulator, monitor input end, jack interface, die casting aluminium seat and solid ground end, stainless steel casing front end is provided with power supply communication pilot lamp, LCDs, stainless steel casing rear end is provided with die casting aluminium seat, die casting aluminium seat is provided with monitor input end by insulator, die casting aluminium seat is also provided with jack interface, bottom die casting aluminium seat, is provided with solid ground end; Described monitor input end is connected with lightning arrester base.
As preferably, described monitor also comprises current transformer, and current transformer is serially connected in arrester ground loop.
As preferably, described LCDs with milliammeter, filth is shown and counter is connected.
The beneficial effects of the utility model: structure is simple, easy to use and reliable, can effectively detect lightning arrester inherent vice, find fault at any time, avoid Explosion of on Arrester, reduce accident rate.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
With reference to Fig. 1-2, this embodiment is by the following technical solutions: electrical leakage, discharge monitor for lightning arrester, comprise stainless steel casing 1, power supply communication pilot lamp 2, LCDs 3, insulator 4, monitor input end 5, jack interface 6, die casting aluminium seat 7 and solid ground end 8, stainless steel casing 1 front end is provided with power supply communication pilot lamp 2, LCDs 3, stainless steel casing 1 rear end is provided with die casting aluminium seat 7, die casting aluminium seat 7 is provided with monitor input end 5 by insulator 4, die casting aluminium seat 7 is also provided with jack interface 6, solid ground end 8 is provided with bottom die casting aluminium seat 7, described monitor input end 5 is connected with lightning arrester base.
It should be noted that described monitor also comprises current transformer, current transformer is serially connected in arrester ground loop.
In addition, described LCDs 3 with milliammeter, filth is shown and counter is connected.The situations such as the milliammeter in monitor, for monitoring the leakage current (peak value) by lightning arrester under working voltage, can judge whether lightning arrester inside makes moist, and whether element is abnormal; Filthy table is for monitoring the size (namely filthy size) of the filthy electric current of arrestor porcelain bushing outside; Operation counter then records the superpotential action frequency of lightning arrester.
The collection of this embodiment monitor voltage phase signal adopts capacitance type sensor, near high-voltage charged body during installation.The collection of monitor current signal adopts high precision small area analysis current transformer, is serially connected in arrester ground loop.Monitoring means display mode: adopt low power consumption liquid crystal display.
This embodiment can detect lightning arrester inherent vice effectively, finds fault at any time, avoids Explosion of on Arrester, reduces accident rate; Arrester on-line monitoring system makes the monitoring of lightning arrester more at any time, more accurately, substantially increases the operational reliability of lightning arrester.Analyze reason from the angle measured and lightning arrester field accident, monitoring lightning arrester runs total current can more effectively reflect lightning arrester ruuning situation.Lightning arrester on-line monitoring remote transmitting system can run total current by Real-Time Monitoring lightning arrester, record lightning arrestor movement number of times, and by real time data teletransmission, highly sensitive, reliability is strong, and reading is quick and easy.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
