Description

Misplug preventing structure for drawer of low-voltage cabinet Technical Field The utility model relates to the technical field of transformers, and particularly provides an anti-misplug structure of a low-voltage cabinet drawer. Background In low voltage drawer switch cabinet applications, as the number of circuits increases, the number of drawer units increases. In the case where the number of drawer units is large, the drawer units are liable to be mixed at the time of assembly. When the drawer units are mixed, that is, when one drawer unit is put into the other drawer units, a series of serious problems of the loop, such as failure of the loop function, error of signal feedback, malfunction or failure of the protection device, etc., can be caused. These problems not only affect the normal power supply of the power system, but also may cause safety accidents, resulting in economic loss and social impact. In order to prevent the drawer units from being assembled in a mixed mode, the prior art is generally provided with a plug pin matched with the jack, the drawer units are provided with the plug pin, the cabinet body is provided with the jack, and when the plug pin can be accurately inserted into the jack, the drawer units are indicated to be assembled in the correct positions, so that the drawer units are prevented from being assembled in a mixed mode. However, the installation accuracy requirement of the plug pin and the jack is high, the jack is required to be parallel to the axis of the plug pin, when the axis of the jack and the axis of the plug pin are not parallel, obvious resistance is applied when the drawer unit is installed into the cabinet body, the drawer unit cannot be installed, and operators judge that the position of the drawer unit is incorrect, so that the installation of the drawer unit is affected. Particularly, the bolt is easy to deform in the long-term use process, so that the bolt is difficult to insert into the jack, and an operator considers that the loading position of the drawer unit is incorrect, and the loading of the drawer unit is affected. Therefore, in the prior art, error prevention is realized through the cooperation of the bolt and the jack, so that the drawer unit is not smooth in the loading process due to the accuracy problem of the bolt and the jack, and the operator misjudges the drawer unit to be loaded. Disclosure of utility model The utility model provides an anti-misplug structure of a low-voltage cabinet drawer, which is used for solving the problems that the precision requirement of an identification mechanism formed by matching an existing bolt and a jack is high, and the bolt cannot be smoothly inserted into the jack due to the precision problem, so that the misjudgment of an operator is caused, and the loading of a drawer unit is influenced. The technical scheme of the utility model is as follows: the utility model provides a low-voltage cabinet drawer prevents mistake and inserts structure, including the cabinet body and two at least drawer units, the cabinet body is used for installing each drawer unit, still include first mistake that prevents inserting the inserted sheet and the mistake is prevented to the second, first mistake that prevents inserting the inserted sheet and be connected with the cabinet body, the mistake is prevented to the second is prevented inserting the inserted sheet and is connected with the drawer unit, first mistake that prevents inserting the inserted sheet and the mistake is prevented preventing to the second and insert the inserted sheet position and correspond, first mistake that prevents inserting the inserted sheet is provided with first fender piece and first vacancy of leaving, the second is prevented inserting the inserted sheet and is provided with second fender piece and second and leaves the vacancy, the size and the position that the vacancy was left to first fender piece corresponds with the second, the size and the position that leave the vacancy were left to the first fender piece passes from the second when making the drawer unit put into the unit. In the scheme, when the drawer units are installed in the unit cells of the cabinet body, the drawer units can be determined to be installed in the correct unit cells only by the fact that the first blocking piece does not collide with the second blocking piece. That is, when the first blocking member can pass through the second clearance, the second blocking member can pass through the first clearance, so that the drawer unit can be confirmed to be mounted in the correct unit cell. The first blocking piece and the second blocking piece do not need to be matched, and when the first blocking piece collides with the second blocking piece, the fact that the drawer unit is installed in an incorrect position is indicated. Because the first blocking piece and the second blocking piece are not matched, the processing precision requirement is low, the situation that the dr
