Abstract
The utility model discloses a secondary loop voltage and current combined connection box. The utility model comprises a box body and a box cover, wherein current junction blocks and voltage junction blocks which are mutually insulated and separated are arranged in the box body; junction holes are arranged on the box body; clamping seats are arranged on the voltage junction blocks; the clamping seats corresponding to two voltage junction blocks are connected with fuse wires. When a voltage is too high, the fuse wires cut off voltage input and output connecting wires to make a whole circuit not supply power so as to effectively avoid destruction generated by the high voltage and simultaneously guarantee the reliable operation of a secondary loop.
Description
Technical field the utility model relates to a kind of electric energy metrical special junction box, specifically is used for the secondary circuit electric current and voltage associating terminal box of electric power meter.
Background technology its structure of electric energy metrical special junction box (also claiming the associating terminal box) commonly used at present comprises box body and lid, voltage terminal, current terminal is arranged in the box body and be connected slide plate.Ease of connection in the existing terminal box between contiguous block is loosening, causes trouble to wiring, also causes extra error to electric energy metrical simultaneously, when serious even can damage circuit, electrical equipment and junction box body.At this situation, the applicant has designed a kind of secondary circuit electric current and voltage associating terminal box and has proposed patent application (application number is 200420090836.7), insulation voltage tagblock and electric current tagblock separately is set in the box body, played tangible improvement effect.But this terminal box itself does not have safeguard measure for too high voltages, can not effectively avoid the destruction of bringing because of overtension.
The secondary circuit electric current and voltage associating terminal box that the summary of the invention technical problem to be solved in the utility model is to propose a kind of damage that can effectively avoid overtension to bring, guarantee the secondary circuit reliability service.
For solving the problems of the technologies described above, the utility model secondary circuit electric current and voltage associating terminal box comprises box body and lid, be provided with electric current tagblock and voltage tagblock that mutually insulated separates in the described box body, described box body is provided with wiring hole, described voltage tagblock is provided with deck, is connected with fusible link on the deck of described corresponding two voltage tagblocks.
Above-mentioned secondary circuit electric current and voltage associating terminal box, the outer cover of described fusible link is provided with carries band.
The utility model is owing to adopted above-mentioned technical pattern, when overtension, fusible link can cut off voltage into and out of wiring, and entire circuit can not be powered, thereby can utilize terminal box itself effectively to avoid the destruction that produces because of overtension, also can guarantee the secondary circuit reliability service simultaneously.The outside sheathed band of carrying of fusible link can be convenient to install or change fusible link.
Description of drawings is described in further detail the utility model below in conjunction with drawings and embodiments.
Fig. 1 is the structural representation of the utility model terminal box box body.
Embodiment as shown in Figure 1, the secondary circuit electric current and voltage associating terminal box that is used for three-phase and four-line " three advance three goes out " the voltage mode of connection comprises transparent box cover (not shown) and box body 1, be provided with electric current tagblock 2 and voltage tagblock 3 that mutually insulated separates in the box body 1, be equipped with wiring hole 4 corresponding to each tagblock 2,3 place on the sidewall of box body 1, each tagblock 2,3 is provided with wiring hole and fixing threaded hole 5.Each voltage tagblock 3 is provided with elastic clamp seat 8, is connected with fusible link 9 on the elastic clamp seat 8 of corresponding two voltage tagblocks 3, and the outer cover of fusible link is provided with to insulate to carry is with 10.Among the figure, the connecting hole between 6 expression box bodys 1 and lid, the installing hole of 7 expression terminal boxes, 11 expression zero line tagblocks.
Claims (2)
1, secondary circuit electric current and voltage associating terminal box, comprise box body and lid, be provided with electric current tagblock and voltage tagblock that mutually insulated separates in the described box body, described box body is provided with wiring hole, it is characterized in that, described voltage tagblock is provided with deck, is connected with fusible link on the deck of described corresponding two voltage tagblocks.
2, secondary circuit electric current and voltage associating terminal box as claimed in claim 1 is characterized in that the outer cover of described fusible link is provided with carries band.
