Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of coincidence controller, especially to a plug -in coincidence controller. BACKGROUND

[0002] The coincidence controller is an automatic control device for detecting line faults and controlling the automatic reclosing operation of circuit breakers in power systems. When a short circuit or other fault occurs in the line, the circuit breaker will trip to cut off the power supply. The coincidence controller will attempt to reclose after a set time interval to restore power supply. If the fault has been eliminated, the reclosing is successful. If the fault still exists, the circuit breaker will trip again to prevent equipment damage.

[0003] Traditional coincidence controllers usually require complex installation steps, including screw fixing, cable connection, etc. The installation process is time-consuming and laborious. When the controller needs to be maintained or replaced, multiple fixed components must be removed, which is complex and increases maintenance time and cost.

[0004] When disassembling the traditional coincidence controller, the operator needs to loosen the fasteners of the controller with one hand and hold the controller with the other hand to prevent it from falling, which causes difficulty in operating when disassembling and replacing the plug-in controller. Secondly, when the controller is installed in the power distribution cabinet, it needs to be fixed by screws and other fasteners. When disassembling, a disassembly tool is needed, which is not convenient for quick disassembly. SUMMARY

[0005] The utility model aims at providing a plug-in coincidence controller, which can avoid the situation that traditional coincidence controllers usually require complex installation steps, including screw fixing, cable connection, etc. The installation process is time-consuming and laborious.

[0035] In order to improve the fixing effect of controller body 1, annular slot 4 is opened in the upper end of plug 3, and the end of plug 3 is arc-shaped structure, which facilitates the entry of plug 3 into bushing 5, sliding hole one 6 is symmetrically opened on both sides of bushing 5, plug rod 8 is slidably arranged in sliding hole one 6, one end of plug rod 8 is provided with wedge-shaped block, spring 9 is sleeved on plug rod 8, when plug 3 enters bushing 5, wedge-shaped block is pushed outward, after wedge-shaped block enters slot 4, spring 9 promotes wedge-shaped block to be inserted into slot 4, plug 3 is fixed, and controller body 1 is preliminarily installed.

[0036] Further, sliding hole two 7 is symmetrically opened on the lower side of bushing 5, bottom rod 10 is slidably arranged in sliding hole two 7, and bottom rod 10 is slid out to be located at the bottom of plug 3, to enhance the stability of plug 3.

[0037] As shown in Figure 3 And Figure 7 As shown, positioning mechanism is arranged on the lower side of mounting plate 2, and the lower end of controller body 1 is fixed by the positioning mechanism.

[0038] Specifically, the positioning mechanism comprises slide rails 11 located on both sides of the mounting plate 2, through holes are formed in four sides of the slide rails 11, an adjusting sleeve 13 is slidably arranged in the slide rails 11, a connecting rod 14 is slidably arranged in the adjusting sleeve 13, one end of the connecting rod 14 is fixedly connected with a fixing sleeve 15, and the end of the fixing sleeve 15 is in "U" shape structure, so as to wrap and fix the controller body 1.

[0039] In addition, a screw rod 16 is threadedly connected to one end of the adjusting sleeve 13, and the end of the screw rod 16 is rotatably connected with the connecting rod 14, so that the connecting rod 14 can be moved by rotating the screw rod 16, so that the fixing sleeve 15 moves away from or approaches the controller body 1.

[0040] In order to improve the stability of the connecting rod 14, a long groove 17 is formed in the upper side of the adjusting sleeve 13, and the protrusion provided on the upper end of the connecting rod 14 slides in the long groove 17, so that the connecting rod 14 and the adjusting sleeve 13 can be effectively prevented from being separated.

[0041] Furthermore, one side of the adjustment sleeve 13 is connected to the rack 18, and the rack 18 slides in the through hole opened in the mounting plate 2. The through hole on one side of the slide rail 11 is connected to the through hole opened in the mounting plate 2, and a rotating rod 19 is rotatably provided on the back side of the mounting plate 2. The two ends of the rotating rod 19 are respectively connected to gears 20. The gear 20 is engaged with the rack 18.

When rotating the screw 16, the connecting rod 14 can fix the controller body 1 with the fixing sleeve 15. Of course, when disassembling, the plug rod 8 can be pulled outward to separate the plug 3 from the socket 5, and then the fixing sleeve 15 can be moved away from the controller body 1 to complete the disassembly of the controller body 1, eliminating the need for disassembly tools. When disassembling the controller body 1, the controller body 1 is fixed by the positioning mechanism. At this time, the maintenance personnel can free their hands to pull out the plug rod 8, and move the controller body 1 downward through the positioning mechanism to separate the plug 3 from the socket 5.
