[0002] During teaching, practical assessment and skills appraisal, it is necessary to set faults on the generator set for students to diagnose. This is usually done by destroying the lines, pipes or other components of the generator set, which is time-consuming and labor-intensive and can easily damage the equipment. Especially for practical assessment, each person needs to temporarily set a fault, which reduces the efficiency of the examination.

[0008] Furthermore, a first label is provided on the surface of the control panel at a position corresponding to the manual switch, and the first label is used to display the name of the manual switch.

[0009] Furthermore, a second label is provided on the surface of the control panel at a position corresponding to the manual switch, and the second label is used to display the fault type controlled by the manual switch.

[0012] Furthermore, the manual switch and the remote control switch are connected in series.

[0013] Furthermore, the manual switch and the remote control switch are both normally closed, and when they are disconnected, the generator set is controlled to malfunction.

[0014] Furthermore, it also includes a box body, in which a terminal block is arranged, the control panel is fixed in the box body, and the lower part of the box body is provided with an inlet and outlet groove for routing the terminal block.

[0029] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0031] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Example 1

[0033] like Figure 1-Figure 9 As shown, the present invention provides a diesel generator set fault detection and troubleshooting training and assessment device, including a generator set and a control panel 1, on which a plurality of fault control switches are provided. The fault control switches are connected to the generator set through wires to control the generator set to generate different types of faults respectively.

[0034] Specifically, the two pins of the fault control switch are connected to wires. When the wires are connected to the wires of the unit, they are connected with open wire noses, so they can be connected at the wiring terminals without cutting or damaging the wires. Note that the wire numbers of the switch wires are consistent when connected to the wires of the unit. For example, if one wire of switch K01 is connected to the wire of the unit, then the other wire of switch K01 should be connected to the other terminal of the wire on the terminal block. If the wire is the unit's throttle control valve circuit, because the control valve is the valve body that controls the unit's oil circuit switch and the amount of oil supply, switch K01 controls the unit's oil circuit fault, and it is marked as an oil circuit fault under switch K01.

[0035] By analogy, the diesel generator set fault detection and troubleshooting training and assessment device can control the generator set to have other different fault types through other fault control switches, and realize the preset generator fault type, so that different types of faults can be quickly set for different students and candidates during teaching, practical assessment or skill appraisal, saving fault setting time and improving examination efficiency. For specific fault types and setting methods, see the following embodiment 5.

[0039] On the surface of the control panel 1, above the handle of the manual switch K, a corresponding name label of each manual switch K is affixed, such as K1, K2, K3, K4, K5, K6, K7, K8, K9, K10, K11, K12, to facilitate distinguishing and identifying different manual switches K.

[0040] On the surface of the control panel 1, below the trigger of the manual switch K, a second label 4 is affixed to each manual switch K to identify the fault type, such as starting circuit fault, positive pole short circuit fault, negative pole short circuit fault, fuel indication signal fault, excitation circuit fault, DC motor charging fault, oil pressure signal fault, water temperature indication signal fault, busbar current signal fault, phase failure fault, speed signal fault and oil circuit fault, which correspond to the names on the first label 3 of the manual switch K one by one, so as to conveniently distinguish and identify the fault types controlled by different manual switches K.

The manual switch K and the remote control switch J are connected in series. Both the manual switch K and the remote control switch J are normally closed, and when they are disconnected, the generator set is controlled to generate a fault.

[0043] Specifically, the remote control switch J is common in the art, and its structural principle is not described in detail. The remote controller 2 and the remote control switch J have antennas for remote control. The remote control switch J is arranged on the inner side of the control panel 1 in the box 6 (hidden inside the control panel 1 and the box 6), and is arranged in series with the manual switch K. Both the remote control switch J and the manual switch K are normally closed contacts, which are disconnected when controlled, and the generator is set to a corresponding fault.

[0044] A button for each remote control switch J is set on the remote controller 2, and a third label 5 is set on the button (sprayed), such as fault 1, fault 2, fault 3, fault 4, fault 5, fault 6, fault 7, fault 8, fault 9, fault 10, fault 11, fault 12, so as to easily distinguish and identify different remote control switches J.

[0045] The third label 5 of the button on the remote controller 2 and the first label 3 of the manual switch K on the surface of the control panel 1 have corresponding serial numbers or descriptions, so that the remote controller 2 and the manual switch K can respectively set corresponding faults for the generator.
