Description

Technical Field

[0001] The utility model relates to the technical field of current sources, in particular to an adjustable direct current source. Background Art

[0002] The internal resistance of the current source is large relative to the load impedance, and fluctuations in the load impedance will not change the current. It is meaningless to connect a series resistor in the current source loop because it will not change the load current or the voltage on the load. Such resistors should be simplified on the schematic diagram. The load impedance only makes sense when connected in parallel to the current source, and it is a shunt relationship with the internal resistance.

[0003] At present, most current sources are generally used in conjunction with an ammeter when in use. When in use, the ammeter needs to be connected to the current source through a connecting line. When the current source needs to be used outdoors, some locations with uneven terrain are often encountered. At this time, it will cause the current source and the ammeter connected thereto to be inconvenient to place stably, which makes it inconvenient for staff to operate. Therefore, it is necessary to design a current source that can effectively place the current source stably outdoors and facilitate the placement of the ammeter to solve the above problems.

[0025] See also Figure 1 and Figure 3 In this embodiment, in order to better dissipate the heat of the current source body 01, the heat dissipation component includes an air inlet 02, a filter 021 and a heat dissipation fan 022. There are several air inlet holes 02 that are evenly arranged at the top of the current source body 01 near the front and at both sides near the front;

[0026] A plurality of through holes are opened on the back of the current source body 01. The number of the cooling fans 022 corresponds to the number of the through holes and are all installed on the inner wall of the through holes. The number of the filters 021 corresponds to the number of the through holes and are all installed on the outer side of the through holes.

[0027] When the current source body 01 is in use, the three cooling fans 022 on its back will start at the same time to discharge the heat generated inside the current source body 01 to the outside. The filter 021 will block dust from entering to a certain extent. When heat is dissipated, external air will enter the current source body 01 from the air inlet 02, and finally be discharged from the cooling fan 022 at the through hole with the heat inside the current source body 01.

[0028] See also Figure 1 and Figure 2 It should be noted that, in order to facilitate the use of the current source body 01 outdoors, there are two support legs 031, which are rotatably connected to the positions on both sides of the current source body 01 near the front, and the fastening bolts 03 are threadedly connected to the rotational connection between the support legs 031 and the current source body 01;

[0029] There are four pads 032 which are respectively arranged at the four corners of the bottom of the current source body 01 .

The pads 032 are made of rubber.

[0030] When it is necessary to support and use outdoors, first loosen the fastening bolt 03, and then adjust the angle of the supporting foot 031 by rotating so that the current source body 01 is in a roughly horizontal state after being placed. After adjusting the angle of the supporting foot 031, tighten the fastening bolt 03 to fix the supporting foot 031. When placed, one side of the supporting foot 031 is in contact with the ground, and the other side of the pad 032 is in contact with the ground to form a triangular support, making the support more stable.

[0031] See also Figure 1 and Figure 2 Specifically, in order to facilitate the stable placement of the ammeter and the connection between the ammeter and the current source body 01, one side of the support plate 04 is connected to the top of the current source body 01 through the first hinge 041, and there are two support rods 043, which are both connected to the bottom of the support plate 04 away from the first hinge 041 through the second hinge 042;
