The invention discloses an electronic power soft starter, and relates to the technical field of power equipment soft start, the electronic power soft starter comprises a silicon controlled rectifier heat dissipation system, a silicon controlled rectifier trigger system and a soft start control system, the silicon controlled rectifier heat dissipation system adopts a double heat dissipation mode of oil immersion and water cooling, and three-phase six silicon controlled rectifier elements are immersed in insulating oil; the bottom of the oil box is placed in the water box; according to the silicon controlled rectifier trigger system, two silicon controlled rectifiers in each phase are connected in anti-parallel and are connected with relay coils through buttons, and contacts of relays are connected with control electrodes of the silicon controlled rectifiers. According to the electronic type electric power soft starter, a contactless spark design is adopted, sparks generated by a traditional mechanical contact type starter are effectively avoided, and the safety production level is improved; and meanwhile, the short-circuit instantaneous breaking protection circuit breaker is adopted, so that the safety protection performance of the equipment is further enhanced. The heat dissipation mode is innovative, oil immersion and water cooling are combined, the heat dissipation cost is reduced, and hot water can be recycled.

The utility model discloses a direct current charging pile hanging gun socket with an indication function, which comprises a gun body socket, a normally open switch device, a relay and a hanging gun state indication module, a trigger mechanism of the normally-open type switch device penetrates through the switch groove and is exposed out of the inner surface, and the relay is electrically connected with the normally-open type switch device and the gun hanging state indicating module. According to the utility model, through the arrangement of the normally open switch device, the relay and the gun hanging state indication module, a simple and efficient indication function is formed; according to the utility model, the normally open switch device is matched with the lock catch mechanism, so that the triggering mode is simpler and firmer.

This invention provides a method and device for monitoring leakage in a converter valve, belonging to the field of leakage monitoring technology. It includes a valve tower, with a water collection tray fixedly connected to its bottom. The inner bottom wall of the water collection tray has an inclined surface sloping towards the center. A water inlet cylinder is fixedly connected to the inner bottom wall of the water collection tray. The outer top wall of the water inlet cylinder has several first locking grooves arranged in a circumferential array. The outer wall of the water inlet cylinder near the first locking grooves has several water inlet channels arranged in a circumferential array. First locking posts are symmetrically fixedly connected to the outer wall of the water inlet cylinder near the bottom. A monitoring component is also included, used to monitor leakage in the converter valve, and connected to the water inlet cylinder. This invention, by setting up a monitoring component, simplifies the alarm triggering method when coolant enters the device, and avoids the influence of colloidal substances on the alarm triggering accuracy.
