Abstract
The utility model relates to an electricity meter box with the avoiding fraudulent use function, which is composed of an electricity meter, a knife switch, a fuse and a box body. The box body is composed of an electricity meter branch box, a knife switch and a fuse branch box. The electricity meter branch box is provided with an electricity meter, a zero line electroscope and a mechanical door opening counter. The door is provided with a built-in lock, wherein, the zero line electroscope is the same with the common electroscope, and is composed of the connection of a neon tube and resistor, and is connected with the zero line of the introducing circuit. Furthermore, the door of the electric meter branch box is inlaid with transparent materials. The entire box body is made of iron, and is firm, fire-resistant and beautiful. Utilizing the transparent plate on the door can inspect the electric meter from the outside of the box, observes the wire connection case of the electric meter and the opening times of the box door. Moreover, the electric meter is locked by a door lock so that the normal operation of the electricity meter is ensured, which prevents the electric larceny.
Description
The utility model relates to a kind of anti-electricity-theft ammeter box.
The ammeter box of existing metering electricity consumption quantity mostly is installed in ammeter, fuse in same wooden case or the iron case, owing to need often to change fuse, makes outside ammeter also is exposed to, and opportunity is provided for the stealing personnel; Or change the ammeter wiring privately, or take other measure, ammeter can not normally be moved, can not reflect true electricity consumption quantity, bring unnecessary loss for country and electric industry management department.
The purpose of this utility model is that a kind of anti-electricity-theft ammeter box will be provided, and it can make ammeter normally move, and prevents stealing.
The purpose of this utility model is achieved in that this anti-electricity-theft ammeter box, constituted by ammeter, fuse, plug-in strip and casing, casing is made up of ammeter branch mailbox and fuse, plug-in strip branch mailbox, ammeter, zero line electroscope, the mechanical type register that opens the door is housed in the ammeter branch mailbox, on the door built-in lock is housed, wherein the zero line electroscope is identical with common electroscope, is connected with resistance and is constituted by a neon tube, and it is connected on the zero line of bay-line; In addition, stud with transparent material on the ammeter door-dividing, whole box body is by iron casing, firm, fire prevention, attractive in appearance.Utilize door to go up transparent panel, can outside case, check ammeter, observe ammeter wiring situation and chamber door and open number of times, add the door lock locking again, thereby guaranteeing that ammeter runs well prevents stealing.
Advantage of the present utility model:
1. guarantee that ammeter normally moves, prevent stealing: independent separately because of ammeter and fuse, plug-in strip, branch mailbox is installed.In the ammeter branch mailbox, be provided with the zero line electroscope, can prevent that reconfiguration enters meter circuit privately, the register that opens the door, preventing unpacks arbitrarily fiddles with ammeter, adds the hidden door lock, reach multiple-protection, this door lock key makes the people can't arbitrarily change ammeter traveling rule by the unified keeping of managerial personnel.Plug-in strip, fuse branch mailbox are as establishing door lock, and then its key is taken care of by user oneself, so that change fuse.
2. simple in structure, to draw materials easily, cost is low, and is safe in utilization, convenient: because of ammeter material therefor, element, be existing product, other optional equipment as neon tube, resistance and the machinery counter etc. that opens the door, has also very easily been bought on the market; Adopt the iron-clad casing, can be because of the electrical equipment loose contact, circuit generates heat and breaking out of fire; Easy, small investment are installed, original ammeter, fuse can be recycled; In addition, by the transparent material on the chamber door, can unpack can check in power consumption and unpack the door number of times.
3. energy savings is avoided waste, and is convenient to the power supply department toll administration, helps improving people's moral level.
The utility model concrete structure is provided by following examples and accompanying drawing thereof.
Fig. 1 is the utility model front view.
Fig. 2 is the utility model left view.
Fig. 3 is the utility model internal part scheme of installation.
Describe in detail below in conjunction with accompanying drawing:
With reference to Fig. 1～3, this anti-electricity-theft ammeter box is made of ammeter, fuse, plug-in strip and casing, and this casing is combined by ammeter branch mailbox 1 and fuse, plug-in strip branch mailbox 4, and each branch mailbox has the chamber door of independent folding; Ammeter 9 is installed in ammeter branch mailbox 1, and zero line electroscope, the mechanical type register 8 that opens the door is equipped with built-in lock 3 on the door; The first half of ammeter branch mailbox chamber door studs with transparent material 2.Described zero line electroscope is identical with general electroscope structure, is formed by connecting by a neon tube 11 and resistance (1M Ω) 12, and electroscope is connected on the zero line of introducing power circuit.
In the utility model in the ammeter branch mailbox the every switching of chamber door once, the feeler lever that must touch counter once shows door opening times from the teeth outwards, simultaneously, as with the zero line of ammeter and live wire reversal connection the time, must make neon tube luminous, can find immediately that ammeter can not normally measure electricity consumption, thereby prevent stealing.During actual the use, can one the case one show, also can in one the case a plurality of ammeters be housed, according to circumstances select for use.
In addition, the user is carried out limit when power supply, can in case, install restrictor additional, or earth leakage protective device, the protection facility of alternate manner also can be installed as required as need.Mounting means can adopt bright extension or adopt and partly inlay the semi-trailer installation, and is optional according to condition.
Casing is to be fixed on the wall 5 with bolt 6 among the figure, and the case side has window shutter 7, be beneficial to aeration-cooling, transparent material 2 useable glass or transparent plastic sheet.
