DETAILED DESCRIPTION

[0019] The utility model discloses further illustrate below combining with the drawing and specific embodiment:

[0020] Specific embodiment, such as Figures 1-4 The utility model provides a modular installation's relay middle level life monitoring platform, including monitoring control cabinet and load cabinet, the load cabinet includes the cabinet body 1 and is located in the relay and load module 12 in the cabinet body 1, the relay is connected with monitoring control cabinet by load module 12, be provided with pull -out groove 2 and heat dissipation pipeline 3 on the cabinet body 1, and the pull -out groove 2's slot cavity forms the installation unit for the relay placement, and the head of installation unit along horizontal direction is provided with air intake 4 and air outlet 5 respectively, heat dissipation pipeline 3 is fixedly connected with the cabinet body 1, the lower end of heat dissipation pipeline 3 is the open end for air intake, and heat dissipation window 6 that links to each other with air outlet 5 is provided on heat dissipation pipeline 3, and cold air enters installation unit along air intake 4 and is discharged into heat dissipation pipeline 3 along air outlet 5 and forms ventilation and heat dissipation.

[0021] At present, the heat dissipation of the cabinet body 1 is mainly passive heat dissipation or active fan heat dissipation, and the heat dissipation effect is poor, which influences the working state and service life of the relay in the cabinet body 1. Meanwhile, the cabinet body 1 of the load cabinet is generally composed of multiple layers of partition plates 10 for fixing the relay. When the relay is installed into the load cabinet, it needs to be installed step by step from the inside to the outside. When the distance between the adjacent partition plates 10 is close, the relay close to the central area is difficult to install and disassemble, and therefore, the distance between the partition plates 10 is usually increased. However, this measure will cause the waste of space in the load cabinet and reduce the number of relays that can be installed in the unit volume of the load cabinet.

[0022] Firstly, the pull-out groove 2 that can be disassembled is arranged in the cabinet body 1 of the load cabinet in the utility model, which can be taken out during installation and disassembly, and facilitates the installation and disassembly of the relay, so that the distance between the adjacent partition layers in the cabinet body 1 does not need to be increased, the number of relays that can be tested in the unit volume is improved, and the problem of waste of space in the cabinet body 1 is avoided.

[0023] Meanwhile, in order to improve the heat dissipation effect of the installation unit, the heat dissipation pipeline 3 is further arranged in the load cabinet, the chimney effect is formed by using the heat dissipation channel, the air inlet 4 of the pull-out groove 2 can be provided with an air inlet fan, the top air outlet of the heat dissipation pipeline 3 is provided with an air outlet fan 11, the dashed cube at the top of the heat dissipation pipeline 3 in the figure is the air outlet fan 11, the cold air outside is sucked into the installation unit by the air inlet fan for cooling, and then the hot air carrying heat is introduced into the heat dissipation passage by the air outlet fan 11 and discharged along the heat dissipation pipeline 3, so that the purpose of high-efficiency heat dissipation is achieved.

[0024] In addition, each installation unit is provided with a load module 12, which includes a load, a monitoring circuit and a driving circuit. The cable of the load module 12 is routed through the wiring groove provided on the pull-out slot 2 and connected with the monitoring and control cabinet through the load cabinet. The load module 12 is provided with an interface for connecting a relay. The relay is directly connected with the interface to perform life test. The modular arrangement of the load and the circuit can reduce the occupancy of the internal space of the load cabinet 1, which is beneficial to the heat dissipation of the internal space of the cabinet 1 and the installation of the relay.

[0025] As shown in Figures 3-4 Fig. 1, the cabinet 1 is provided with a plurality of guide rails 7 in the vertical direction for the horizontal sliding of the pull-out slots 2. The pull-out slots 2 are provided with sliding sheets 8 on both sides for sliding cooperation with the guide rails 7. The pull-out slots 2 have the freedom of being pulled out of and embedded into the cabinet 1 by means of the sliding sheets 8. The guide rails 7 can limit the pull-out slots 2 in the horizontal direction, which facilitates the installation and disassembly of the pull-out slots 2 and the cabinet 1. Meanwhile, the guide rails 7 also have the function of guiding to ensure that the air outlet 5 of the pull-out slot 2 is aligned with the heat dissipation window 6.

[0026] In addition, the side walls of the guide rails 7 and the side walls of the pull-out slots 2 are provided with threaded holes. When the air outlet 5 of the pull-out slot 2 cooperates with the heat dissipation window 6 of the heat dissipation channel, the threaded holes of the guide rails 7 and the threaded holes of the pull-out slots 2 are matched. Then, the guide rails 7 and the pull-out slots 2 can be fixedly connected by using bolts to ensure the position of the pull-out slots 2.

[0027] The air outlet 5 of the installation unit is provided with a skirt 9 arranged along the sliding direction of the pull-out slot 2. The skirt 9 is matched with the heat dissipation window 6 of the heat dissipation pipeline 3. The inner side end surface of the pull-out slot 2 abuts against the side wall of the heat dissipation pipeline 3 to form a seal. The air outlet 5 is connected with the heat dissipation window 6 by means of the skirt 9 to form a heat dissipation passage. On the one hand, the skirt 9 has the function of positioning. When the skirt 9 is embedded into the heat dissipation window 6, the surface position is aligned. By means of the friction force between the skirt 9 and the heat dissipation window 6, the limit function can be achieved to ensure that the inner side end surface of the pull-out slot 2 abuts against the heat dissipation pipeline 3 to form a seal, thereby avoiding the retention of hot air in the installation unit and the inability to discharge the hot air along the heat dissipation pipeline 3 to form efficient heat dissipation. On the other hand, the skirt 9 also has the function of guiding the hot air in the installation unit to hinder the hot air discharged by other installation units from entering the installation unit.

[0028] The middle part of the pull-out slot 2 is provided with a vertical partition plate 10 arranged along the sliding direction of the pull-out slot 2. The slot cavity of the pull-out slot 2 is divided into a plurality of installation units by means of the partition plate 10. The partition plate 10 divides the pull-out slot 2 into a plurality of installation units. The partition plate 10 has the function of blocking the mutual transmission of heat to reduce the total heat discharge in a single installation unit. Each installation unit discharges heat individually to shunt the heat, thereby achieving the purpose of efficient heat dissipation.
