Problems solved by technology

[0002] At present, the installation of the resistance module directly cooled by seawater is complicated, the anti-vibration and shock ability is poor, and the withstand voltage level and dielectric strength cannot meet the needs of high-demand equipment.
[0003] This kind of resistance module usually has a large distance between the resistance and the resistance, and the resistance is long, resulting in a large volume of the entire device, which brings great inconvenience to maintenance and installation. Considering that there is no extra space for installation in some special cases, the installation volume is large The non-pure water cooling equipment needs to be optimized with more demanding materials and structures during design, so as to adjust the volume and performance indicators of the resistance module

Embodiment 1

[0024] refer to figure 1 , figure 2 As shown, the present invention discloses a water-cooled resistance module. Since the length of the resistance module is determined by a specific resistance value, an overly long resistance tube will make it prone to cantilever phenomenon during installation. In order to avoid this situation, A plurality of middle support plates 5 need to be arranged in parallel at the same distance, and a middle protective sleeve 6 is welded on the middle support plate 5. The structural parts can be welded with corrosion-resistant materials (such as: titanium alloy, stainless steel, etc.). A number of resistors 7 located on two concentric circles are fixed on the middle support plate 5, that is, a number of resistors 7 are arranged in a central ring and divided into two layers inside and outside. equal, and also includes connecting copper bars 11 connected to both ends of the resistor 7, one end of the resistor 7 is provided with a sealing flange 8 and an...

Embodiment 2

[0027] The difference from Example 1 is that the protective sleeve 2 at the non-outlet end is connected with a head 1 through a baffle 4. Since the non-outlet end is sealed with the head 1, it can be installed in the equipment and can be used for a long time. Water (such as: tap water, lake water, river water, impure water) is directly cooled. The baffle plate 4 is composed of double-layer partitions. The connection part of the outlet end is in contact with impure water. The insulation resistance of the resistance module of this structure is greater than 2000MΩ, and it can withstand AC7000V voltage for 1min without flashover and breakdown.

Embodiment 3

[0029] refer to image 3 , Figure 4 As shown, the difference from Embodiment 1 is that the non-outlet end support plate 3 is also provided with a temperature sensor sheath 10, and a temperature sensor 14 is installed on the temperature sensor sheath 10, so that the resistance module It has the temperature signal output capability, and the internal temperature of the resistance module is transmitted by the signal line, so as to avoid the damage of the resistance module due to dry burning.

Abstract

The invention discloses a novel water-cooled resistor module. The novel water-cooled resistor module comprises a plurality of middle part support plates arranged at equal intervals in parallel and middle part protective sleeves arranged on the middle part support plates, wherein a plurality of resistors positioned on two concentric circumferences are fixed on each middle part support plate, and the resistors are equally spaced. The novel water-cooled resistor module also comprises connecting copper bars connected to two ends of the resistors, a sealing flange and a wire outgoing end protective sleeve are arranged at one end of each resistor, and a non-wire outgoing end support plate and a non-wire outgoing end protective sleeve are arranged at the other end of each resistor. Compared with an existing resistor module, the novel water-cooled resistor module can straightly go through non-purified water under an only water-cooled condition to perform long-term stable operation, and the structure is impact while extremely high insulation performance and voltage resistance are guaranteed, so that the maintainability of the resistor module is greatly improved, the maintenance time and cost are reduced, the work efficiency is improved, and the novel water-cooled resistor module has great economic benefit.
