Abstract
The utility model discloses an anti-theft mechanism in a power transformer monitoring system. The anti-theft mechanism comprises a positioning rod, a positioning sleeve, a push switch and an elastic pad, wherein one end of the positioning rod is embedded in the positioning sleeve and is in threaded fit connection with the positioning sleeve, the positioning sleeve is convex inwards to form an annular support table located below the positioning rod, the push switch and the elastic pad are located in the positioning sleeve, the push switch is disposed on the annular support table, and the elastic pad is located between the positioning rod and the push switch. When the anti-theft mechanism is in use, whether a transformer is stolen by a thief is judged according to whether a box cover of the power transformer is opened, the occurrence of false alarming incidents can be reduced, and the anti-theft effect can be improved. The anti-theft mechanism disclosed by the utility model has good waterproof performance and a longer service life.
Description
Technical field
The utility model relates to the transformer anti-theft field, specifically the burglar-proof mechanism in the power transformer supervisory system.
Background technology
Along with the development of society, electric power just enters the rural area from the city, enters remote place from the busiest section, and various transformation facilities are built in a large number in meagrely-populated place, so the stolen event of transformation facility often occurs.Wherein, the ratio of in the transformation facility theft transformer integral body being stolen or stolen copper core in the transformer is higher, and therefore, solving the stolen problem of transformer becomes an important step that prevents that electric power facility is stolen.
In order to prevent that the copper core is stolen in transformer or the transformer, generally near transformer, be provided with now supervisory system, supervisory system gets involved to send alerting signal by the sensor sensing personnel.Existing supervisory system wrong report can occur in animal enters investigative range the time, can affect antitheft effect.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and the burglar-proof mechanism in a kind of power transformer supervisory system is provided, energy false alarm reduction event when it is used for transformer anti-theft, and then can improve antitheft quality.
The purpose of this utility model is achieved through the following technical solutions: the burglar-proof mechanism in the power transformer supervisory system, comprise backstay, locating sleeve, Push switch and cushion, described backstay one end embeds in the locating sleeve and the mode of mating by screw thread is connected with locating sleeve, described locating sleeve convex consists of the ring-shaped bearing platform that is positioned at the backstay below, described Push switch and cushion all are positioned at locating sleeve, and Push switch is placed on the ring-shaped bearing platform, and cushion is between backstay and Push switch.Be used for connecting casing and the case lid of power transformer when the utility model is used, wherein, backstay not an end of connecting positioning sleeve to be arranged at transformer tank external, locating sleeve does not connect an end of backstay and is located in the transformer-cabinet; The utility model guarantees that when mounted backstay makes Push switch closed to the suppressing action power of cushion, and the utility model when using the Push switch external power supply consist of the closed-loop path.
All be connected with electric wire on two wiring pins of described Push switch, be serially connected with connection resistance on any wire in two wires that Push switch connects.The two wire external power supplys that the utility model connects by Push switch, wherein, output level was stable when connection resistance was used for guaranteeing the utility model application.
Protect for butted line resistance, described connection resistance is positioned at locating sleeve.
Be provided with the first cushion block between described cushion and the backstay, be provided with the second cushion block between cushion and the Push switch.After setting up the first cushion block and the second cushion block, cushion does not directly act on Push switch and backstay, but comes transition by the first cushion block and the second cushion block, can guarantee effect power apply uniformly, and can avoid the cushion local pressure and distortion occurs.
For the ease of drawing materials and saving cost, described backstay is bolt, and described cushion is resilient rubbber cushion.
Compared with prior art, the utlity model has following beneficial effect: (1) the utility model comprises backstay, locating sleeve, Push switch and cushion, one-piece construction is simple, be convenient to realize, when the utility model is used under the effect of backstay cushion make Push switch closed, two pin short circuits of Push switch, show as low level, after if the robber back-outs backstay in the locating sleeve, cushion disappears to the suppressing action power of Push switch, and Push switch resets, and the Push switch bipod shows the level identical with supply voltage, supervisory system is then sent corresponding control according to the variation of Push switch level, and then improves antitheft effect; The case lid whether the utility model opens transformer by the robber to judge whether transformer is stolen, can avoid erroneous judgement, improves antitheft quality.
(2) the utility model Elastic pad is between backstay and Push switch, backstay one side is located at outside the casing when using because of the utility model, if when having a small amount of water to enter in the locating sleeve through the gap between backstay and the locating sleeve, cushion can be Push switch and provides and block, and then can reduce the probability that Push switch damages, the life-span when prolonging the utility model application.
