The beneficial effects of the utility model are, magnetic flux interference when shielding case body makes it avoid being subjected to the transformer operation, the temperature detecting precision height, remote monitoring current signal and R485 communication interface can be provided, be convenient to remote monitoring transformer temperature regime, be mainly used in dry-type transformer, also be applicable to other transformer.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a schematic perspective view, and Fig. 2 is a schematic rear view, and Fig. 3 is a casing seam crossing U-L template synoptic diagram, and Fig. 4 is temperature acquisition and control loop principle schematic.
Among the figure, 1 casing, 2 lids, 3LED display, 4 sound and light alarm lamps, 5,6 temperature acquisitions and control loop, 7 connection terminals, 8 communication interfaces, 9 U templates, 10 L templates, the strong electromagnetic radiation ripple of A casing outside, the light current magnetic radiation ripple of B box inside after the seam crossing decay.
(5) embodiment
Accompanying drawing 1-4 is a kind of specific embodiment of the present utility model.
Temperature control equipment of the present utility model, comprise that inside is provided with the casing 1 of temperature acquisition and control circuit 6, is installed in sound and light alarm lamp 4 and temperature indicator on the casing, casing is ganoid cuboid, adopt open type structure on one side, lid 2 is positioned at the front of casing, sound and light alarm lamp and temperature indicator are positioned at the top of lid, and the bottom of lid is provided with door 5, and the seam crossing of casing is made up of the U-shaped plate 9 and the L shaped plate 10 of the back consolidation of pegging graft.Box back surface is provided with R485 communication interface 8 and connection terminal 7.Temperature indicator is a light-emitting diode display 3, is equipped with in the casing to be attached thereto 4-20mA change-over circuit and the external temperature instrument port that connects.
Temperature control equipment of the present utility model, adopt embedded or wall-hanging installation, shielding case body 1 plays the diffusing outward magnetic field Isolated Shield effect of transformer, to guarantee the operate as normal of attemperating unit internal circuit, its shielding principle is: have cover 2 and door 5 casing adopt the higher aluminium zine plate that covers of surface smoothness to make, and adopt open type structure on one side, to reduce total gap length; The casing seam adopts U-L template structure, and through repeatedly reflection, refraction, its energy is consumed the strong electromagnetic radiation ripple A of casing outside in a large number, thereby reduces the interference of external electromagnetic radiation to inner temperature acquisition and control loop between metallic walls like this.The light current magnetic radiation ripple B after the seam crossing decay is just very little to the influence of whole temperature control equipment for box inside, can ignore.LED display device and acousto-optic alarm lamp are installed in casing the first half, provide temperature value to show and overtemperature sound and light alarm signal.Adopt light-emitting diode display to show the three-phase temperature and the environment temperature of transformer, 4-20mA remote monitoring current temperature signal is provided, for user's external temperature instrument leaves interface, band R485 communication interface 8 also has functions such as fan starting, overtemperature alarm.
Temperature control equipment of the present utility model, principle of work is: temperature acquisition and control loop are shown the temperature data that collects after treatment by LED, and the overtemperature alarm signal is passed to the sound and light alarm lamp that the volume that is installed on the casing is the 10cm/80 decibel through inner microrelay, prompting overtemperature alarm signal passes through the spread of the rumours of R485 communication interface to Control Room with treated temperature data signal with 4～20mA current signal form simultaneously.
