Abstract

The utility model provides a high pressure metering cabinet which is provided with a sealed chamber with a language alarm function. The utility model is mainly used for metering places, such as industrial and mining enterprises, unmanned transformer substations, etc. The utility model has a main structural style that the interior of a sealed cabinet which is provided with a support skeleton is provided with a plurality of partition boards, the inner chamber of the cabinet is divided into a mutual inductance chamber, a chamber of electricity consumption meters, and a chamber for an alarm unit and terminals, wherein, the three chambers are mutually independent and are combined, and a language alarm circuit which is provided with aloudspeaker and a net type alarm is connected with a calculating device. The utility model has the advantages of reasonable design, compact structure, convenient manufacture and maintenance, obvious alarm, automatic meter reading, etc., and is a replacing product of ZL-10 type high pressure metering cabinets which are universally adopted at present.

Description

The multifunctional high pressure metering cabinet

The utility model relates to a kind of electric power metering device, is mainly used in the larger power user metering, also can be used for big industrial user, airport, harbour, hotel, residential quarter and electric substation's electric-power metering, its suitable power measures range is 50HZ, 10KV, the metering of 35KV electric pressure.

Present factories and miness; the rural area; enterprise; electric power metering devices such as residential area; generally adopting XXBO1-4 is totally-enclosed suspension watt-hour meter box; meter reading glass and chamber door are arranged on the panel; a little lock is housed or on chamber door and frame, stamps two apertures respectively on the door; then in the lead sealing; the meter reading personnel was to the doorstep by view window direct-reading data in every month; press the account clearing then; even ammeter fault or think other reason; also can't learn inner case; because of power supply department has regulation; the meter reading personnel checks meter by all means; the dress table personnel game clock case of just having the right; yet accident has generation often; stealing thief stealing; threatened for the safety of the person and equipment, sustain a loss for country and power supply enterprise economically, particularly society goes up making the lead sealing poor management at present; forming the lead sealing pliers of stealing electricity thief use mixes the spurious with the genuine; general technology is to be beyond recognition, and because of equipment failure, as voltage transformer (VT) once or during the secondary side fuse failure; high-voltage metering cubicle; because of table meter decompression, produce negative error, perhaps stop to walk; if the metering chamber door is illegally opened, also can cause stealing.

The purpose of this utility model is to provide a kind of closed cells combination or version, and has centralized and unified management user profile, by public telephone network or professional telephone network and power carrier, formation can be noted the electric quantity data of each spaced point in the electrical network to timing automatic in real time, and but timing automatic ground is sent to the electric administrative department Master Control Center with each stoichiometric point electric quantity data, and can be with metering cabinet electricity consumption situation on-site monitoring, and can be when stealing, the on-the-spot warning automatically and the remote auto warning, and alerting signal is sent on the Master Control Center of electric administrative department and management of power use personnel's the mobile phone or beeper, has highly sensitive monitor function, by telephone wire can be directly to the electric power metering device of electric-power metering cabinet in the defence area, steal electric situation and the equipment failure situation is judged, so that the electrical management personnel are treatment facility fault and quick and precisely launching an attack timely, the electric equipment fault is in time handled, guarantee that electric power metering device safety obtains ensureing the most completely, avoid stealing the economic loss that electricity brings to power supply enterprise.

The utility model adopts the closure cabinet type structure, in establish support frame and dividing plate, the cabinet inner chamber is divided into a plurality of independently cells, general layout bottommost is terminal chamber and alarm system, the middle part is a watt-hour meter, the top is that the electric power incoming line high-tension cable is connected with mutual inductor, the door face board of each cell is loaded onto view window and door lock, the language alarm circuit that has loudspeaker and stop-loss pressure instrument links to each other with each chamber door, electron watt-hour meter links to each other with electric quantity collector, user's electric weight can be delivered to main control computer and power department management centre computer after by collector.

The utlity model has reasonable in designly, compact conformation is made advantage easy to maintenance, particularly enclosed construction, has significantly reduced the incidence of accident, and behind measuring apparatus cutout, decompression, the metering door-lock opening, the warning effect is obvious, has more practicality.

Below be described further in conjunction with the accompanying drawings.

Fig. 1 is the utility model structural front view;

Fig. 2 is the utility model structure vertical view;

Fig. 3 is the utility model decompression, cutout, improper open alarm device electrical schematic diagram and computing machine Automatic meter reading system schematic diagram.

Among the figure: 1, shell 2, view window 3, dividing plate 4, view window 5, dividing plate 6, view window 7, base plate 8, top cell 9, the automatic alarm door lock 10 of dual fail-safe, the automatic alarm door lock 11 of dual fail-safe, the automatic alarm door lock 12 of dual fail-safe, entrance hole 13, entrance hole 14, wire hole 15, wire hole 16, wire hole 17, current transformer 18, voltage transformer (VT) 19, terminal box 20, phase three-wire three electronic type multi-function watt-hour meter 21, stop-loss pressure instrument 22, electric quantity collector 23, language alarm 24, loudspeaker 25, accumulator jar 26, dc power supply 28, communication network 29, phone 30, mobile phone 31, computing machine.

Among Fig. 1, being fixed in shell (1) on the support frame makes cabinet make three side sealing to close form, dividing plate (3) and dividing plate (5) are divided into separately independently cell with the cabinet chamber, and door lock (9), (10), (11) that view window (2), view window (4), view window (6) and dual fail-safe are reported to the police automatically are housed on each cell door-plate.Top cell (8) is the High-Voltage Insulation cable socket, can with current transformer (17), voltage transformer (VT) (18) carries out primary side and connects, its secondary side is connected with phase three-wire three electronic type multi-function watt-hour meter (20), stop-loss pressure instrument (21) current return is connected with the current return of phase three-wire three electronic type multi-functional current table (20), the voltage circuit of stop-loss pressure instrument (21) is in parallel with the voltage circuit of phase three-wire three electronic type multi-function watt-hour meter (20), cabinet middle part cell is a phase three-wire three electronic type multi-function watt-hour meter (20), the bottom of cabinet bulk cell is that language alarm (23) is connected with loudspeaker (24), and this warning circuit principle as shown in Figure 3.
