capacitor discharge device

technical field

The utility model relates to a discharge device, in particular to a capacitor discharge device, which is applied to the discharge of capacitors after power failure in electric power production. the

Background technique

Capacitor discharge is an important link before capacitor power outage maintenance. There is residual charge in the capacitor. When the equipment is overhauled, if the operation or maintenance personnel touch the outlet, the capacitor will discharge, causing direct harm to the human body. At present, in the system, there is no special tool for discharging capacitors. Usually, ordinary ground clamps are used to discharge directly, and the outlet terminals of the capacitors are not shorted. The positive and negative plates of the capacitor cannot be reliably connected. The contact area of the discharge is small, and the residual charge of the capacitor cannot be completely discharged. , and the time required for bottle by bottle discharge is long, the discharge workload is large, time-consuming and laborious, and it is easy to cause safety hazards. Therefore, in order to improve work efficiency, it is necessary to study new capacitor discharge methods. the

Detailed ways

Example

As shown in Figure 1, the fixed frame consists of a horizontal fixed rod and a vertical fixed rod to form an L-shaped fixed frame. The L-shaped fixed frame is an L-shaped metal tube, and a universal joint is installed on the vertical fixed rod to adjust the required angle. The universal joint is equipped with positioning bolts, which are used to fix the L-shaped fixed frame at the adjusted angle. The tail end of the longitudinal fixed rod is connected with the insulating rod; the horizontal fixed rod is connected with an adjustable ruler frame, and the adjustable ruler frame is provided with a fixed-length hole, and different ruler holes are selected to realize the variable ruler. A discharge clamp is arranged above the horizontal fixed rod and the adjustable ruler frame. The discharge clamp is composed of two elastic copper sheets to form a duckbill-shaped discharge clamp. One end of the discharge clamp is a duckbill-shaped opening, and the other end of the discharge clamp is a discharge frame connecting ring. The above-mentioned copper sheet has a certain degree of elasticity. When the outlet end of the capacitor is inserted into the duckbill, the copper sheet can press it tightly; when it is pulled out, the copper sheet returns to its original shape; The L-shaped fixed frame and the adjustable ruler frame are short-circuited through the short-circuit connecting ring between the connecting rings of the discharge frame; the L-shaped fixed frame is equipped with a ground wire connection piece, and the ground wire connection piece is connected with the copper ground wire The other end is grounded.

The adjustable ruler frame is a straight metal tube. the

The short-circuit connecting wire is a multi-strand annealed copper wire with a diameter not less than 6mm. the

Before the capacitor is discharged, adjust the adjustable ruler frame according to the distance between the outlet terminals of the capacitor and fix it. Closely connect the copper ground wire to the discharge frame through the ground wire connecting piece before use. When discharging, connect the discharge frame to the insulating rod, and ground the ground wire reliably. Then adjust the universal joint, adjust the discharge frame to a suitable angle, and fasten it with positioning bolts. Insert the duckbill clip of the discharge rack into the outlet of the capacitor to complete a discharge. the
