Abstract
The utility model discloses an on-line signal fixture for the continuous monitoring of electric terminal overfire, comprising a body, a temperature indicating sheet, a red signal flag and a cover plate. The utility model has the advantages of simple structure, easy fabrication, low cost, convenient installation, wide applicability and obvious and simple monitoring. The temperature of all electric terminals and jumper wire lap joints in a transmission and transformation power distribution system can be monitored by the signal fixture continuously. After the electric terminals and the lap joints are provided with the signal fixture, if the temperature of the electric terminals and the lap joints surpasses the permissible value, the temperature indicating sheet melts, the cover plate of the signal fixture disengages from the temperature indicating sheet, and the red signal flag is shown to make the inspector understand fully at one glance.
Description
The utility model belongs to the defeated distribution technique field that becomes.
In the defeated transformation and distribution system, electric connecting point, various wire jumper lap joints, because the existence of contact resistance will produce heat by electric current, the line contact of different materials allows different contact temperatures according to the rules.Sometimes because there is bigger contact resistance in joint loose contact (oxidation and rusting etc.), will produces the too high lead that burns out of contact temperature by electric current and cause fault.Therefore become in the distribution operational process defeated, often the temperature of monitoring electric terminal.The temperature of operation field monitoring various contacts often adopts two kinds of voltage method and thermometry, and voltage method promptly directly rides over the contact two ends with voltage table and surveys its voltage drop, and the both end voltage of surveying the same length of this lead then compares the judgement contact temperature.Another kind is to use infrared thermometer, measures contact temperature.The former measures not only inconvenience but also can not continuous monitoring, and is not suitable for the monitoring of farsighted contact, and is also relatively more dangerous during measurement.Latter's instrument and equipment is complicated heavy, manipulate inconvenient general workman and be difficult for grasping, and the equipment price costliness can not continuous monitoring.
The utility model is in order to solve the practical difficulty of operation field monitoring contact temperature, and realizes the purpose of the overheated online watch-keeping temperature of safe ready contact.
The utility model is made of body, sheetlike temperature indicator, danger signal flag and cover plate etc.Have one connecting hole is installed on the body, its pore size is as the criterion to cooperate electrical equipment that coupling bolt is installed, and does to install and uses.There is a temperature indicating film trap centre of body, and sheetlike temperature indicator just is contained in this groove, sheetlike temperature indicator with heat conduction preferably glue tightly stick in the temperature indicating film trap, the sheetlike temperature indicator outside surface is convenient to cover plate and is adjacent to sheetlike temperature indicator a little more than the outerplanar of this groove.Temperature indicating film trap below also has a square signal flag chamber, indoor dress danger signal flag, and the danger signal flag is folded up, and it is indoor that an end is fixed on signal flag, and the other end is fixing on the cover board.The danger signal flag is made with the red glass paper tape or with other red plastic bands.There is a liquid-leaking nozzle temperature indicating film trap inboard, and when sheetlike temperature indicator melted, from then on its liquation flowed out in the hole.The cover plate upper end is hinged with body, and the lower end is not connected with body, and cover plate can overturn around pin joint, and the cover plate inboard is brushed with red lacquer, with the good glue of heat conduction cover plate is sticked on the sheetlike temperature indicator outside surface during lid cover plate.Attention can not be bonded on the body.Body is bent at an angle between installation connecting hole and temperature indicating film trap, make cover plate and the earth surface level built that an angle is arranged during installation, and cover plate down, like this when electric terminal surpasses allowable temperature, heat is passed to sheetlike temperature indicator by body, make the sheetlike temperature indicator fusing, its liquation overflows from liquid-leaking nozzle, cover plate breaks away from sheetlike temperature indicator, own wt by cover plate is sagging, just pulls out the danger signal flag, and the personnel that patrol and examine just can obviously see the inboard red color of danger signal flag and cover plate, this just represents that this contact has surpassed allowable temperature, must handle immediately.Body and cover plate all are to make available copper, aluminium etc. with the material that conducts heat preferably.Cover plate and body are hinged to be wanted flexibly.According to the permission rated temperature that the material of electric terminal and lap joint is stipulated, select the temperature of fusion of sheetlike temperature indicator.For example the temperature of fusion of sheetlike temperature indicator has 55 ℃, 60 ℃, 70 ℃, 80 ℃, 90 ℃, 100 ℃ etc.
Advantage of the present utility model, this apparatus structure is simple, and is easily manufactured, can the watch-keeping contact temperature.This device is applied widely, and defeated transformer and distribution station has contact to be suitable for.This device is on-the-spot easy for installation, and general workman all can be competent at.Compare with existing supervision means, reduce labour intensity greatly, increase work efficiency.Reduce cost.
Description of drawings: accompanying drawing 1, accompanying drawing 2 are body front elevation and cut-open view, and among the figure: (1) is body, are to be made by good copper or the aluminum metallic material that conduct heat, and according to used occasion difference, body are curved different angles.(2) connecting hole is installed, whole device is installed on the contact that needs to monitor with this hole.(3) liquid-leaking nozzle, when sheetlike temperature indicator melts its liquation thus orifice flow go out.(8) temperature indicating film trap, this groove is communicated with liquid-leaking nozzle (3), and sheetlike temperature indicator just is contained in this groove.(9) pin hole, body (1) and the hinged usefulness of cover plate.(7) there are two screw holes (10) signal flag chamber at the bottom of the chamber, for an end of fixing danger signal flag is used.
Accompanying drawing 3, accompanying drawing 4 are front elevation and the cut-open views that install the overheated on-line continuous supervisory singal device of electric terminal of sheetlike temperature indicator and danger signal flag, among the figure: (1) body.(2) connecting hole is installed.(3) liquid-leaking nozzle.(4) sheetlike temperature indicator sticks on the sheetlike temperature indicator trench bottom with the good glue that conducts heat, and the sheetlike temperature indicator outside surface is convenient to cover plate (5) and is close on the sheetlike temperature indicator (4) a little more than the outside surface of temperature indicating film trap.Cover plate (5) upper end is hinged with pin and body (1), and following of cover plate (5) has two screw holes, is used for fixing an end of danger signal flag (6), and the other end of danger signal flag (6) is fixed in the signal flag chamber (7).Long the folding up of danger signal flag (6) ensconced in the signal flag chamber (7).Cover plate during installation (5) sticks on the outside surface of sheetlike temperature indicator (4) with the good glue that conducts heat, and notes between cover plate (5) and the body (1) glue being arranged.
