Problems solved by technology
[0006] Due to the limitation of the load components, the existing high-power load boxes are bulky, complicated to operate, have particularly high requirements on the cooling system, and the safety and reliability are not high enough
For some customers who are mainly used to control high-load and high-current high-power components, it is impossible to find a corresponding large load to simulate the actual situation of the user's site, or to temporarily complete the test temporarily by other loads. problem with control

Embodiment Construction
[0023] The outdoor resistance box of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0024] Such as figure 1 As shown, the outdoor resistance box of the present invention includes: a box body 1 with rainproof grids 4 on both sides of the box body 1 and an anti-water top plate 5 at the top of the box body 1 . The load 2 is arranged in the box body 1, and the control box 10 is connected with the load 2 for controlling the load 2 to form different power combinations. The branch terminal is connected to an external incoming power supply through the wire outlet hole 12, and the other end is connected to the load 2 and the control box 10. Two exhaust fans 3 are arranged in the box body 1 and connected with the control box 10 to serve as heat dissipation devices for the box body 1 .
[0025] Such as figure 2 As shown, the control box 10 includes the first three-phase circuit breaker QF1, the second three-phase circu...

The invention provides an outdoor resistance box comprising a box body, a load disposed in the box body, a heat-dissipating device disposed in the box body, a control box connected with the load and the heat-dissipating device, and branching terminals connected with an external inlet wire power supply, the load, and the control box. The outdoor resistance box is reasonable in electrical line and may select and control a first breaker to a fourth breaker indoors in order to obtain loads with different capacities and satisfy the requirements of product tests. By dissipating heat with an exhaust fan, the volume of the outdoor resistance box is decreased and the service lives of resistors are prolonged. The use of the outdoor resistance box is not restricted by outdoor environment and the safety and the use efficiency of outdoor resistors are improved.
Description
technical field [0001] The invention relates to a device in the field of electrical technology, in particular to a load resistor that can be controlled indoors and is not restricted by outdoor environmental conditions. Background technique [0002] The high-power load box is used as a simulated load in large-scale generators, high-power UPS, inverter power supplies, and large-scale storage battery systems, and can complete the detection of system parameters and functions. The high-power load element in the high-power load box is an important part of the load box, and it is the key to enabling the equipment to achieve functions such as miniaturization, multi-function, and flexibility. [0003] Currently commonly used load elements are: [0004] Water resistance: In a large pool filled with pure water, an electrode is placed to form a resistance as a load element. However, the water resistor is bulky, and the device is fixed and cannot be moved; a large amount of water is ev...
