Abstract
The utility model relates to an electricity metering box suitable for one-apartment and one-meter unified installation of electric power departments. An incoming line end is provided with a plug and a socket which are connected by a conducting line and an electric meter; the electric meter is connected with an air circuit breaker by the conducting line. Thus, the utility model has the advantages of reasonable structural design, high safety, non-perishable fire disaster happening, etc.
Description
The utility model relates to a kind of gauging table case, particularly a kind of illumination electric degree gauging table case, and it mainly is suitable for, and power department is unified installs that Every household has an ammeter uses.
Structure such as Fig. 1, Fig. 2, shown in Figure 3 of many families watt-hour meter scale case in the prior art, it by three utmost point air-breaks 1 ', watt-hour meter scale 2 ', fuse 3 ', plank 5 ' and casing 4 ' form, air-break 1 ' by lead and watt-hour meter scale 2 ' be connected, watt-hour meter scale 2 ' again is by lead and fuse 3 ' be connected, three utmost point air-breaks 1 ', watt-hour meter scale 2 ' and fuse 3 ' all be fixed on plank 4 ' on, plank 4 ' then be fixed on casing 5 ' on; A ' is an inlet wire, and B ' is outlet.This table case remains in actual use in following defective; 1, air-break does not significantly switch on and off a little when switching on and off power supply, thus dangerous when handling failure and transposing watt-hour meter, fuse, when the air-break spanner is malfunctioning, can't cut power supply especially, at this moment accident is just inevitable; 2, air-break is used as master switch in this structure, so all must turn off when maintenance, processing, transposing shunt watt-hour meter, has increased frequency of power cut like this; 3, the fusible link in the fuse is mated by each user oneself, it is excessive to occur the capacity coupling like this, lose overcurrent protection, cause the overload of watt-hour meter and household electrical appliance to damage, simultaneously, in multilayer group building user, sometimes the fusible link of a family blows, take the fusible link of another family to put, make another family electricity that broken, easily cause neighbourhood's dispute; 4, electric elements all are contained on the plank, when current overload causes that electric elements are overheated, and fire hazardous.
The purpose of this utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of reasonable in design, safe and reliable, the illumination electric degree gauging table case that is difficult for having an accident are provided.
The purpose that the utility model proposed can be achieved through the following technical solutions: it comprises watt-hour meter scale and casing, the watt-hour meter scale is installed in the casing, its design feature is: also design has plug, socket and two utmost point air circuit breakers, socket links to each other with inlet wire, plug is connected with the watt-hour meter scale by lead, and the watt-hour meter scale is connected with air-break by lead again.
Description of drawings is as follows:
Fig. 1 is the front view of watt-hour meter scale case in the prior art.
Fig. 2 is the side view of watt-hour meter scale case in the prior art.
Fig. 3 is the wiring diagram of watt-hour meter scale case in the prior art.
Fig. 4 is a front view of the present utility model.
Fig. 5 is a side view of the present utility model.
Fig. 6 is a wiring diagram of the present utility model.
Following the utility model will be in conjunction with the accompanying drawings, and be described in further detail by embodiment.
Referring to Fig. 4, Fig. 5, Fig. 6, this watt-hour meter scale case is made up of plug 8, socket 7, watt-hour meter scale 2, two utmost point air-breaks 9 and casing 4, plug 8, socket 7 are installed in the terminal box 6, socket 7 links to each other with inlet wire A, plug 8 is connected with watt-hour meter scale 2 by lead 10, watt-hour meter scale 2 is connected with two utmost point air-breaks 9 by lead 10 again, and they are installed in the casing 4, and all are fixed on the batten 5 that is surrounded by metal skin; At this, two utmost point air breaks 9 play overcurrent, protection, and can replace with the one pole air-break, and plug 8 is single-phase blind plug, and socket 7 is an electrically conductive socket.A is an inlet wire, and it can be single-phase or three-phase and four-line, and B is outlet, uses for the user.
Watt-hour meter scale 2 and plug 8 sockets 7 in this casing 4 can be installed according to number of users, and promptly an Every household has an ammeter plug has been avoided using with mutually and neighbourhood's dispute.
The utility model compared with prior art has the following advantages: 1, structural design is closed Reason, inlet wire is connected on the plugs and sockets, at each minute family processing, transposing kilowatt-hour meter and two utmost point air During breaker, need only transfer to plug, obviously outage, user power utilization is independent of each other, and guarantees Workmen's personal safety; 2, when user's overload power utilization or when other fault occurring, Two utmost points or one pole air-break energy automatic cut-off power guarantee household electrical appliance and other facility Be not damaged; 3, owing to designed the batten that is surrounded by metal skin, can avoid the initiation of fire.
