Description

Electrician's skill training operation circuit module

The utility model belongs to the teaching mould technical field, specifically, is used for electrician's patch panel module that the electrician makes skill training in fact exactly.

In the electrical teaching of school especially skilled workers school, except allowing the student grasp certain knowwhy, more be to want the student to possess stronger operating ability, the student of electrician specialty, the expertly various basic operation circuits of winding.Yet, in existing school instruction, be mostly to make the wiring that some coarse, simple and crude Electrical Engineering Practice modules start to learn some operation circuits for the student according to the needs of teaching by teacher oneself.These Electrical Engineering Practice modules normally teacher are made according to own understanding and teaching needs to teaching material, randomness is bigger, there is not standard, do not possess versatility yet, a kind of module may can only be used for training and connect a few operation circuit, the practical operation knowledge standard that causes the student to acquire differs, and level is uneven, being poor in basic training of grasp; On the other hand, make different patch panel module for different basic controlling circuit exercises, meeting is waste material and man-hour too much, and every of these module all need to connect dragging motor usually, and cost is too high; Simultaneously, do not have unified demonstrator, brought certain inconvenience yet to teacher's teaching; In addition, what traditional electrical teaching terminal block, circuit adopted all is hard laying, causes that student's wiring speed is slow, inefficiency, and technical standard lags behind the trend of incompatible modern electrotechnics development.

The purpose of this utility model provides in order to solve the problem that runs in the middle of the reality teaching just and is exclusively used in the unified module that operation circuit wiring training is used in a kind of electrician's skill training, this module is made by certain standard, can be used to train the winding of various basic controlling circuits, make a module just can train the operation circuit of various modes, replace motor with pilot lamp simultaneously, make training module no longer need to dispose dragging motor, cost of manufacture reduces, and whole circuit adopts soft laying, can improve wiring efficient, and adapt to new technical standards.

The purpose of this utility model is achieved by the following technical solution.

This electrician skill training operation circuit module is that the wire casing plate is installed on working plate, the components and parts that are arranged on the working plate have voltage table, reometer, pilot lamp, position switch, pushbutton switch, also are provided with automatic air-break switch, supply socket, three-phase fuse, two-phase fuse, a winding tentaculum, one group of time relay, one group of electrothermal relay and connecting terminal block; Voltage table is connected with air switch, and reometer is connected in series mutually with supply socket; Pilot lamp, position switch and pushbutton switch all are connected with connecting terminal block with lead.

The location arrangements of each components and parts on working plate is divided into left and right two big zones, two big zone bit devices all adopt horizontal mode, left area first row is arranged in order air switch, three-phase fuse, two-phase fuse and socket, second row is arranged the contactor and the time relay, the third line is arranged electrothermal relay, fourth line is arranged connecting terminal block, between per two row components and parts the wire casing plate is installed all, and the whole periphery on the left side zone also is equipped with the wire casing plate; Zone, the right first row is arranged voltage table and reometer, and second to fourth line arrangement pilot lamp, fifth line arrangement position switch, the 6th row arrange buttons switch; The quantity of set components and parts is 1 of air switch, 1 of three-phase fuse, 1 of two-phase fuse, 1 of socket, 1～6 in contactor, 1～2 in the time relay, 1～3 of electrothermal relay, 1 of connecting terminal block, 1 of voltage table, 1 in reometer, three groups of pilot lamp, every

group

3,2 of position switchs, 1～4 of pushbutton switch; Described wire casing plate is entrenched togather by wire casing base plate and wire casing cover plate; On contactor, also be plugged with auxiliary contact; Set pilot lamp shows low speed, middling speed and the situation that runs up of threephase asynchronous, the reduced-voltage starting working condition that perhaps shows threephase asynchronous star connection or delta connection, perhaps show threephase asynchronous forward and backward working condition, perhaps show threephase asynchronous sequence starting working condition, perhaps show two-speed motor work working order.

This electrician skill training operation circuit module components and parts that electrician's basic controlling circuit is required all reasonably are provided with in order according to the wiring characteristics of operation circuit and are installed on the working plate, and the wire casing plate has been installed on demand on working plate, can between each components and parts, carry out soft laying wiring easily, need the various operation circuits of winding and will connect the lead Hide All in the wire casing plate by teaching; Voltage table that is provided with on working plate and reometer can be used for detecting at any time the ruuning situation of reflection operation circuit, and set supply socket is used for external power supply, so that power supply separates with module, is convenient to the dismounting of module.

The location arrangements of each components and parts on working plate is divided into left and right two big zones and by setting each components and parts is installed, the left area components and parts adopt horizontal mode, what promptly first row was provided with is short-circuit protection and power supply control element, what second row was provided with is the operation circuit element, the third line setting be the overload protection element, the fourth line setting be connecting terminal block, this setup can be when the winding operation circuit, connecting lead does not intersect mutually, need not carry out circuit and put up a bridge in the air, be convenient to operation and winding displacement standard; The quantity of each set components and parts can satisfy the teaching needs of the various basic controlling circuits of middle and high level skill training substantially.The wire casing plate adopts the mode of wire casing base plate and wire casing cover plate tabling, can easily the wire casing cover plate be taken away winding displacement, treat that winding displacement is finished after, with on the wire casing cover plate card, make in the online frid of wiring Hide All again, do not expose substantially, whole module seems neat and artistic.The grafting auxiliary contact can satisfy the needs of various control circuit on contactor; Low speed, middling speed and the situation that runs up of set pilot lamp or demonstration threephase asynchronous, the reduced-voltage starting working condition that perhaps shows threephase asynchronous star connection or delta connection, perhaps show threephase asynchronous forward and backward working condition, perhaps show threephase asynchronous sequence starting working condition, perhaps show two-speed motor work working order, can be implemented in and just finish many, the test of the control circuit of multiple motor on the module, make this module have more versatility.

Below in conjunction with drawings and Examples the utility model is further elaborated.
