Description
Technical field: the utility model belongs to electric power utensil technical field, relates to a kind of electric power metering device.
Technical background: at present, for the little medium-sized and small enterprises of power consumption, power supply department widespread usage batch meter charges.It simple in structure, cost is low, and is easy for installation, and anti-stealing electricity function is strong.But, the electric metering box of this structure, because can not the installation and control switch, can't control automatically the user power utilization amount; The step down side outlet is drawn from the casing top, has installed four copper core binding posts additional, has not only increased equipment investment, has also increased failure rate; In addition, on transformer, install insecurely, influenced security reliability.
Summary of the invention: the technical problems to be solved in the utility model is that technical problems such as insecure be controlled and be installed to common batch meter can't automatically to the user power utilization amount.
For solving the problems of the technologies described above, the utility model electric-power metering control cabinet, it comprises main box, current transformer, charge electric energy table, its main points are also to be provided with in the main box control switch and auxiliary relay; It has an auxiliary box body, and the charge electric energy table is arranged in the auxiliary box body; Between main box and the auxiliary box body, be connected with a metal catheter, lead couples together the electrical equipment in two casings through this conduit; Be provided with two angle steel in the bottom of main box and install relatively, slit of middle formation constitutes a mounting groove, can make main box be fixed on above the transformer firmly; The main box bottom also is provided with four wire holes, and the step down side outlet is drawn from this wire hole.
For the user power utilization amount is controlled automatically, said charge electric energy table is a prepayment meter.
Said prepayment meter also can be that common electric energy meter adds electricity consumption automatic controller formation.
For casing is fixed on the transformer, make the holding screw at transformer top pass slit between two angle steel of main box bottom, last shimming, the usefulness nut is fastening, and two angle steel are pushed down, and casing is fixed.
Be respectively equipped with supporting bracket and mounting bracket in the major and minor casing, supporting bracket is provided with regulating tank, can be according to the device mounting requirement, mounting bracket done moving up and down.
The both sides of major and minor casing are provided with the heat radiation window, and when temperature was higher than external temperature in the casing, the air in the casing can flow out in last heat radiation window, air outside can under dispel the heat and flow in the window, form cross-ventilation.
, control switch less for load current and the little transformer of terminal caloric value also can be installed in prepayment meter and control switch in the main box together, save auxiliary box body.
The utility model electric-power metering control cabinet owing to be provided with control switch in casing, can be controlled automatically to the user power utilization amount; Control switch and electric energy meter are installed in respectively in two casings, make the charge electric energy table be in one independently in the environment, the influence of pyrotoxins such as uncontrolled switch, terminal; In the main box bottom, install relatively with two angle steel, form a slit, constitute mounting groove, the screw at transformer top can be placed in this slit, this casing is placed on the plane of transformer stably, on two or three screws at transformer top, install a pad additional, just angle steel tightly can be pushed down, casing is fixed on above the transformer firmly, this technical scheme can solve common electric metering box unstable problem is installed on transformer, these two angle steel also have an effect, and it can make body structure firmer; The main box bottom, four wire holes have been offered, the step down side outlet is drawn from this wire hole, and common batch meter is drawn lead from the casing top, need install four copper core binding posts additional, compare with common batch meter, this technical scheme had both reduced production cost, had reduced by two points of contact again, reduce failure rate, improved security reliability; In addition, change the charge electric energy table into prepayment meter, after the purchasing electric weight and use up of user, the trip(ping) circuit that can connect control switch automatically has a power failure switch trip, has realized the purpose that the user power utilization amount is controlled automatically.
The utility model electric-power metering control cabinet, simple in structure, reasonable in design, can control automatically the user power utilization amount, casing can be fixedly mounted on the transformer, and the step down side easy-to-connect is safe and reliable.
