Abstract
The utility model discloses a lead seal-screwed anti-electricity theft electricity metering cabinet. Bosses with external threads are arranged on a metering cabinet body enclosing primary terminals of the electricity metering cabinet, anti-electricity theft covers which are screwed on the bosses are arranged, and the primary terminals and connectors for connecting the primary terminals and incoming cables are arranged in the anti-electricity theft covers. Since the anti-electricity theft covers are added on the primary terminals of the electricity metering cabinet, electricity theft can be effectively prevented, and secondary terminals still adopt the conventional lead seals to prevent external wiring. Consequently, the electricity metering cabinet is integrated with an electric system, electric metal is not exposed at all, and the phenomenon of the electricity theft is fundamentally prevented.
Description
Technical field:
The utility model relates to a kind of electric metering box, relates in particular to the anti-electricity-theft electric metering box of a kind of lead sealing screw-in.
Background technology:
High-voltage measuring box claims combination transformer again, is the electric power metering device that electric system is generally used.Along with the development and update of perfect gradually, the power technology of electric system, it is unprecedented that the operating position of High-voltage measuring box reaches.High-voltage measuring box becomes the indispensable measuring apparatus of electric system.
The electric metering box that uses in the electric system at present almost is anti-electricity-theft from secondary aspect anti-electricity-theft entirely, the secondary connection box adds waterproof bulkhead, pressurization stainless steel nameplate plate, outer rivet, add lead sealing or be drawn out to external cabling box (or connection table case), lock, lead sealing from the secondary terminal connections.But occurred in recent years from the phenomenon of once holding stealing of electric metering box (or current transformer), it also is feasible coming inference theoretically, promptly is the current unit CT part with electric metering box, P1, and two connection terminals of P2 connect short circuit.
Electric metering box generally is used for the open air, and overhead about five to seven meters, the industry common saying claims high outage meter again.With the P1 of CT unit, P2 twines with thinner soft copper silk, is difficult for really being found.The electric metering box mounting means that uses in the electric system at present all is the cable connection of three-phase line to be arranged with a terminated line of electric metering box row be connected with bolted.This also provides the external condition of once holding stealing from electric metering box for the lawless person.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of lead sealing screw-in anti-electricity-theft electric metering box, in the hope of preventing the once end stealing of user from batch meter.
The utility model technical solution problem adopts following technical scheme:
The anti-electricity-theft electric metering box of lead sealing screw-in, on the metering casing of the primary connection terminal periphery of described electric metering box, be provided with and have externally threaded boss, and the anti-electricity-theft cover that is threaded with described boss of setting, described primary connection terminal and place in the described anti-electricity-theft cover with the joint of inlet wire cable.
Design feature of the present utility model also is:
The junction of described anti-electricity-theft cover and described boss offers bolt hole radially, between described anti-electricity-theft cover and the described boss with bolted and with lead sealing.
The outer wall of described boss is axially offered groove along it, and described groove extends to the groove that forms " L " shape on the metering casing of boss bottom.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utility model electric metering box adds anti-electricity-theft cover on the primary connection end, can carry out effectively anti-electricity-theftly, and the secondary connection terminal still adopts traditional lead sealing to prevent external connection.Make electric metering box and using electricity system be connected as a single entity, do not have any electricity consumption exposed metal/bare metal outside, fundamentally solved stealing electricity phenomenon.
Anti-electricity-theft cover employing screw-in of the present utility model presses with batch meter and connects, and is easy for installation, quick.Screw and promptly expose the lead sealing bolt hole after putting in place, for the anti-electricity-theft usefulness of lead sealing.
The utility model is provided with " L " connected in star in the junction of anti-electricity-theft cover and boss and constitutes exhalant canal, even if there is a small amount of rainwater to discharge from exhalant canal immediately, keeps being in all the time in the anti-electricity-theft cover drying regime.And exhalant canal is set to " L " shape, electricity filching person can't make tinsel by and touch live metal positions such as " P1, P2 ".
Description of drawings:
Fig. 1 is the front view of the utility model batch meter; Fig. 2 is the vertical view of Fig. 1; Fig. 3 is the A-A cut-open view of Fig. 2; Fig. 4 is the connection diagram of anti-electricity-theft cover of the utility model and batch meter.
Number in the figure: 1 electric metering box, 2 boss, 3 primary connection terminals, 4 anti-electricity-theft covers, 5 inlet wire cables, 6 bolts hole, 7 grooves.
Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment:
Embodiment: in conjunction with Fig. 1-4, the anti-electricity-theft electric metering box of lead sealing screw-in of present embodiment, on the casing of electric metering box 1, be provided with and have externally threaded boss 2, boss 2 is in the periphery of primary connection terminal 3, and the anti-electricity-theft cover 4 that is threaded with boss 2 of setting, primary connection terminal 3 and place in the anti-electricity-theft cover 4 with the joint of inlet wire cable 5.
In conjunction with Fig. 4, the junction of anti-electricity-theft cover 4 and boss 2 offers bolt hole 6 radially, when anti-electricity-theft cover 4 is threaded on the boss 2, in bolt hole 6 with the bolted quadrat envelope of going forward side by side.
Shown in Figure 4, the outer wall of boss 2 is axially offered groove 7 along it, this groove 7 extends to the groove that forms " L " shape on the metering casing of boss bottom, when anti-electricity-theft cover is connected on the boss and after with the bolted lead sealing, can discharge from the water delivering orifice that groove 7 forms if there is a small amount of rainwater to enter in the anti-electricity-theft cover, keep dry state in the anti-electricity-theft cover guaranteeing.
