Accompanying drawing explanation
Fig. 1 is the structural representation of the low pressure electric meter box that provides of the utility model;
Fig. 2 is structural representation during the opening of ammeter chamber in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, so that those skilled in the art can better understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
The present embodiment provides a kind of low pressure electric meter box, as depicted in figs. 1 and 2, comprises control room 1 and ammeter chamber 2 two parts.In described control room 1, be provided with total input-wire switch 3, the top of described ammeter chamber 2 is provided with a plurality of kilowatt-hour meters 4, and bottom is provided with circuit breaker 5.Between described kilowatt-hour meter 4 and circuit breaker 5, can be provided with neutral line short-circuit protector.Junction between described control room 1 and ammeter chamber 2 is provided with wire-passing tube 6, and this wire-passing tube 6, for the inner assembled wire-passing tube that is equipped with cable, is connected in each kilowatt-hour meter 4 by this wire-passing tube 3 by total input-wire switch 3.The control room 1 of the low pressure electric meter box that the present embodiment provides and the outer setting of ammeter chamber 2 have insulating barrier, also or the material of described control room 1 and ammeter chamber 2 be all chosen as insulating material, can avoid the permanent corrosion of low pressure electric meter box and the generation of problem of lightning.
Described ammeter chamber 2 comprises casing 7 and chamber door 8, and as shown in Figure 2, described kilowatt-hour meter 4 and circuit breaker 5 are all arranged at described casing 7 inside.Described chamber door 8 is for sealing described casing 7 from the dead ahead of casing 7, the outer setting jug (being preferably plastic material) of chamber door 8, the center of described chamber door 8 has window 9, and its material can be selected glass etc., so that observe equipment situation and the record data of 2 inside, ammeter chamber.
Design the most special in the present embodiment is, between described chamber door 8 and casing 7, is provided with door lock, and described door lock is preferably electronic lock 12, and described electronic lock 12 is arranged at casing 7 inside, can avoid being arranged at outside and expose to the sun and rain and cause damage.And the mode of unblanking of described electronic lock 12 is by pulse controlled mode, the one end that is specially electronic lock 12 can be connected with pulse detecting equipment, described pulse detecting equipment is realized by hardware circuit, its signal input part connects a holding wire, and one end of this holding wire is exposed to the outside of casing 7, by holding wire, connect signal generation apparatus, as pulse generator.When staff need to detect ammeter or copy power taking meter reading, can be by inputting one end pulse signal in the holding wire one end that is exposed to casing 7 outsides by signal generator, and this signal can be coded signal, with prevent inoperative personnel easily input pulse signal open chamber door 8.After pulse signal input, by pulse detecting equipment, process, if the frequency of pulse signal and amplitude all meet set point, pulse detecting equipment is to electronic lock 12 output unlocking signals, open chamber door 8, by setting different pulse signal frequencies and amplitude for different low pressure electric meter boxes, can prevent that inoperative personnel from opening electric equipment and causing unnecessary unexpected generation.
