Abstract
The utility model discloses an electricity anti-stealing transformer which relates to a distribution transformer and makes a measuring watt hour meter and a transformer integrated for the first time, making altering and destroying watt-hour instruments difficult for users, space saved simultaneously and management convenient. An electric force metering instrument is installed into a sealed box which is installed into the appendix box of a transformer; a mutual inductor is installed into a secondary leading wire and connected with the watt hour meter whose outside is provided with an aluminium cover to prevent magnetic disturbance and also provided with an exhaling tube and a buffer device, so the utility model has the functions of high temperature preventing and incline preventing. Power supplying personnel can record number codes through an observation window, but the number codes can not altered by users.
Description
The utility model relates to power equipment, is specifically related to distribution transformer.
In the distribution transformer that uses, metering device generally separates with the transformer body at present, do not link to each other mutually, thereby the user is easily to the metering that changes instrument.
The purpose of this utility model is that metering device and transformer is integrated, makes the user be difficult to change or destroy the electric degree instrument.Time spent is also saved the space, is convenient to management.
Scheme of the present utility model is that the electric-power metering instrument is packed in the airtight case, this case transformer of packing into is again paid in the case, instrument transformer is packed in the secondary lead wires, again instrument transformer and kilowatt-hour meter are linked up, instrument transformer is contained in the place away from iron core, avoided magnetic disturbance, ammeter is installed the aluminium cover outward, prevents the magnetic interference, there is not oil in the ammeter box, ammeter is contained in the fuel tank bottom, and respiratory siphon is installed, and plays anti-temperature and crosses effect, ammeter box is hung in to be paid in the case, therefore have with the vibration problems that solves antimagnetic, shockproof, anti-inclination function.Illustrate further through the utility model structure below in conjunction with attached power.
Fig. 1 is the utility model structure principle chart.
Wherein 1 is current transformer, 2 attached casees, 3 sealing ammeter boxes, 4 Antimagnetic hoods, 5 three phase watt-hour meters, 6 observation windows, 7 exhaust tubes, 8 porcelain tubes, 9 lead-in wires, 10 buffer units.
With reference to Fig. 1.Kilowatt-hour meter is packed in the sealing ammeter box; this case hangs in the attached case; current transformer is fixed on the low-voltage lead support, and instrument transformer and kilowatt-hour meter couple together with lead, and kilowatt-hour meter is provided with Antimagnetic hood outward; exhaust tube; buffer unit, Antimagnetic hood adopt the 0.5MM aluminium sheet to make, and are enclosed within the outside of kilowatt-hour meter; like this kilowatt-hour meter is protected, not disturbed by external magnetic force.Because ammeter box is in the higher oil of external temperature, and ammeter box inside is air, the oil of outside makes air degree heat, and hot-air is discharged from last exhaust tube, and cold air constantly replenishes from lower inlet duct and forms convection current, makes the kilowatt-hour meter environment temperature constant.Exhale (advancing) tracheae to adopt grease proofing plastic flexible pipe to make up and down, isolate, guarantee not have in the ammeter box oil and infiltrate by joint sealing and oil.Buffer unit adopts hook to make, and when the transformer body tilts, also can make kilowatt-hour meter remain horizontal level.The power supply personnel can pass through observation window recording electrical meter number, and the user then can't amendment record or breaking-up ammeter.
Claims (1)
1, anti-electricity-theft transformer, it is characterized in that kilowatt-hour meter pack into the sealing ammeter box in, this case hangs in the attached case, current transformer is fixed on the low-voltage lead support, instrument transformer and kilowatt-hour meter couple together with lead, kilowatt-hour meter peripheral hardware Antimagnetic hood and exhaust tube.
