Abstract
The utility model discloses a low-voltage knife switch having an interlocking structure. The low-voltage knife switch comprises an interlocking mounting plate (3) and a program lock (2), and is characterized in that the interlocking mounting plate (3) is connected with a knife switch mounting plate, the interlocking mounting plate (3) is connected with the program lock (2), and a lock head of the program lock (2) is correspondingly connected with a knife switch rotating shaft (5) on the knife switch mounting plate. When a knife switch handle (4) is pulled to an opening position (II), a key of the program lock (2) is slidingly connected with the program lock (2) and can exit; when the knife switch handle (4) is pulled to a closing position (I), the key of the program lock (2) is in positioning connection with the program lock (2) and cannot exit, and another key cannot be opened with regard to the knife switch; thus, misoperation is effectively prevented, and accidents are preventing from happening.
Description
Technical field
The utility model belongs to the distribution technique field, relates to a kind of low-voltage knife switch with interlock, particularly BX series rotary low-pressure knife switch.
Background technology
Low-voltage knife switch is applicable to city, township's power distribution network, makes secondary switch disjunction rated load electric current and circuit overload, short-circuit protection.Be specially: insulating power supply, to guarantee the safety of circuit and maintenance of equipment; Or as the load usefulness of not connecting continually and the disjunction rated current is following; The disjunction load is not as connecting continually and low-voltage circuit that breaking capacity is little or directly start small-capacity motor.When knife switch is in open position, can obviously observe, can guarantee circuit maintainer's safety.But in low-voltage equipment, can't interlock between the BX series rotary mechanism in the two-way incoming line cabinet at present, cause easily misoperation to cause accident.
Summary of the invention
The purpose of this utility model be to provide a kind of in BX series rotary low-pressure knife switch the established procedure lock, solved the low-voltage knife switch with interlock that can only unify between two inlet wires knife switch.
The technical solution of the utility model is: it comprises interlocking mounting panel and procedure lock, described interlocking mounting panel is connected with the knife switch mounting panel, be connected with procedure lock, the tapered end of procedure lock and the corresponding connection of the knife switch rotating shaft on the knife switch mounting panel on the interlocking mounting panel.
Further: the knife switch mounting panel is provided with travel switch, knife switch rotating shaft and knife switch handle, and an end of knife switch rotating shaft is connected with the knife switch handle, and during combined floodgate, the knife switch handle is connected with the travel switch trigger button.
Further: when the knife switch handle was got to open position, key and the procedure lock of procedure lock were slidingly connected; When the knife switch handle was got to closing position, key and the procedure lock of procedure lock were located by connecting.
Compare without interlock with existing, interlock of the present utility model is convenient to use, and when the knife switch handle was got to closing position, the key of procedure lock can not withdraw from, and can't open another to knife switch; Therefore, can effectively prevent misoperation, avoid accident to occur.

Fig. 2 is the side-looking structural representation of the utility model embodiment 1.
Embodiment
The utility model can be implemented by technical scheme, and the utility model will be further described by the following examples, yet scope of the present utility model is not limited to following embodiment.
Embodiment 1.
Fig. 1 is to Figure 2 shows that, illustration is as follows: travel switch 1, procedure lock 2, interlocking mounting panel 3, knife switch handle 4, knife switch rotating shaft 5.
Of the present utility model being described as follows: it comprises interlocking mounting panel 3 and procedure lock 2, described interlocking mounting panel 3 is connected with the knife switch mounting panel, interlocking is connected with procedure lock 2 on the mounting panel 3, the knife switch rotating shaft 5 corresponding connections on the tapered end of procedure lock 2 and the knife switch mounting panel.
The knife switch mounting panel is provided with travel switch 1, knife switch rotating shaft 5 and knife switch handle 4, and an end of knife switch rotating shaft 5 is connected with knife switch handle 4, and during combined floodgate, knife switch handle 4 is connected with travel switch 1 trigger button.
During installation, install interlocking mounting panel 3 additional at the knife switch mounting panel, load onto knife switch rotating shaft 5, knife switch handle 4 and travel switch 1 at the knife switch mounting panel; Load onto procedure lock 2 at interlocking mounting panel 3.
When knife switch handle 4 was got to the open position II, the key of procedure lock 2 and procedure lock 2 were slidingly connected, and the key of procedure lock 2 can withdraw from, and extracted another knife switch of operation; When knife switch handle 4 was got to the closing position I, the key of procedure lock 2 and procedure lock 2 were located by connecting, and the key of procedure lock 2 can not withdraw from.Namely can not operate another to knife switch, thereby realize that 2 knife switches can only unify handle! Prevent misoperation!
