Abstract
The utility model relates to a measured type transformer conducting pole, wherein a current transmitter and a current mutual inductor are penetrated through the conducting pole in parallel to be integrally cast with a shell, and the signal output ends of the current transmitter and the current mutual inductor are extended out of the shell through an output interface on the shell. The conducting pole is hermetically and integrally cast with the current mutual inductor, thereby preventing persons from stealing electric energy. When a transformer operates, the current transmitter can measure a primary current on the user high voltage side in real time, and send to a data acquisition unit to process in a wireless mode, the primary current is converted into digital information through an A/D circuit, and is wirelessly transmitted to a background monitoring system to analyze and process after being encrypted, therefore, current value can not be changed by people under the operation, and the electric energy stealing phenomenon can be timely founded out through checking the current data with the current data in an electric energy meter of a user, thereby effectively preventing the electric energy stealing behaviors.
Description
Technical field
The utility model relates to a kind of electric component, is a kind ofly to have electric energy transmitting, measure electric current, electric energy and power, and the measurement type transformer conducting bar with the wireless output function of current signal.
Background technology
Stealing generally is to carry out stealing, particularly large electricity consumer by the means of changing mutual inductor ratio or crossing over the electricity consumption of gauge table meter, and electricity filching behavior remains incessant after repeated prohibition, and the direct economic loss that annual China electrical network causes because of stealing is all up to tens yuan.At present, existing transformer conducting bar function singleness does not have and measures electric current, electric energy and power, and function such as wireless transmission current signal, effectively stops stealing with this.
Summary of the invention
In order to overcome the shortcoming that prior art exists, it is a kind of simple in structure that the purpose of this utility model is to provide, anti-electricity-theft effectively in advance, has electric current, electric energy and the power of measurement, and the measurement type transformer conducting bar of wireless transmission current signal function.
Technical solution of the present utility model is: a kind of measurement type transformer conducting bar comprises conducting rod, shell, described current transducer summation current transformer stack is applied on the conducting rod, the current transducer summation current transformer is covered with shell and pours into an integrated entity with shell, and the output interface of the signal output part of current transducer summation current transformer on shell extends outside the shell.
After adopting above technical scheme, the beneficial effect that the utility model reaches is:
1, the sealing of this transformer conducting bar and current transformer pours into an integrated entity, and the lawless person of stealing can not carry out stealing by the means of changing mutual inductor ratio, can't realize the purpose of stealing.
2, the sealing of this transformer conducting bar and current transducer pours into an integrated entity, during the transformer operation, the current transducer part is measured user high-pressure side primary current in real time, and is sent to the data acquisition unit processing with wireless mode, and primary current becomes digital information through the A/D circuit conversion; After encryption by the wireless background monitoring system analyzing and processing that is sent to, make and in servicely artificially can't change its current value, to the current data in user's the electric energy meter, stealing electricity phenomenon can be in time found with this current data stoning, and electricity filching behavior can be effectively stoped.
The utility model is simple in structure, and cost is low, long service life, and stable signal transmission, power-steeling preventing effect is good, has substituted the transformer end of incoming cables conducting rod of traditional simple function.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, conducting rod 1, shell 2, current transducer 3, output interface 4, current transformer 5.
Embodiment
Below in conjunction with accompanying drawing the utility model and embodiment are further described.
In shown in Figure 1, measurement type transformer conducting bar is integrated by conducting rod 1, shell 2, current transducer 3, signal output part 4, current transformer 5; Shell 2 is closed, and material is the acrylonitrile-butadiene rubber of high insulating property, through the mold pressing pouring one-step forming; Current transducer 3, current transformer 5 are the single turn penetration type, 5 stacks of current transducer 3 summation current transformers are on conducting rod 1, and pour into a seal with the shell of outer cover and be fastened on the conducting rod, reduce the drawback that contact is many, the contact place generates heat easily of circumscribed instrument transformer in the past, also avoided electricity filching person on the secondary line of instrument transformer, to juggle things simultaneously; The output interface 4 of the signal output part of current transducer 3 summation current transformers 5 on shell 2 extends outside the shell, the on high-tension side primary current data of current transducer 3 measuring transformers are sent to the background monitoring system analyzing and processing of collector through power supply department by wireless transmission method.
