The utility model relates to the technical field of electrical safety signboard, and disclose a kind of fixed electrical safety signboard of small standard circuit breaker, including circuit breaker body and the signboard body being set on circuit breaker body, the upper end of the signboard body is fixedly installed with warning sign, under the cooperation of connecting rod, connecting plate, clamping plate, first spring and first sliding slot, make the signboard body be fixed on circuit breaker body, under the cooperation of rubber plate and several grooves, the friction with circuit breaker body can be increased, to avoid signboard body to fall off, under the cooperation of displacement plate, second spring and brake slot, make displacement plate to fill up brake slot, avoid brake false contact closing, so as to cause the electric shock phenomenon of operator, when brake goes to the direction of closing, brake just contact with alarm button, so as to alarm to notify operator, remind operator to put down the work on hand in time, avoid causing electric shock.

The application relates to the technical field of safety signs, and discloses an intelligent sensor induction type electric power safety sign, which comprises a support, a warning board is arranged at the top of the support, a control box is arranged at the middle of the support, and a ground monitoring module is arranged on the control box and used for monitoring whether the ground is electrified. The intelligent sensor induction type electric power safety sign can continuously monitor the potential difference or current change between grounding probes. Once the electric power equipment is electrified, the current flows into the ground through the grounding system, the potential difference or current is changed, the electrification detection circuit immediately detects the abnormality and transmits a signal to a control module, the control module judges the electrification condition according to a preset threshold value, rapidly sends an early warning signal to a remote control center through a wireless communication module, and thus the remote staff can acquire the electrification information in the first time, timely measures are taken for treatment, safety accidents caused by electrification are effectively avoided, and the normal operation of the electric power facilities and the safety of personnel life are ensured.

This invention discloses an outdoor signage energy-storage self-luminous material and its preparation method in the field of energy-storage self-luminous material technology. The energy-storage self-luminous material is a three-layer board, including a top layer, a middle layer, and a bottom layer. The raw materials, by mass percentage, include: 5%-45% dual-mechanism heat-sensitive luminescent powder; 50%-90% thermoplastic matrix; 0.1%-0.5% intelligent photothermal response additive; 4.0%-4.5% reinforcing filler; and 1.2%-2.5% weather-resistant protective component. The dual-mechanism heat-sensitive luminescent powder is composed of SrAl2O4:Eu... 2+ ,Dy 3+ Long afterglow powder and NaYF4:Yb 3+ Er 3+ After mixing with SiO2 upconversion powder, the mixture undergoes sequential chelation with 3-hydroxy-2-naphthoic acid-boronate, inorganic silicon-oxygen copolymerization, and fluorosilane crosslinking, followed by drying and curing. This invention, through the synergistic effect of multiple structures and components, comprehensively optimizes the luminescent properties, weather resistance, mechanical stability, and intelligent adaptability of outdoor signage materials, providing reliable technical support for the upgrading of outdoor signs such as road safety signs, highway signs, and tunnel emergency signs.

The application discloses a site self-healing safety control method for linkage of electrical events of intelligent circuit breakers and order fulfillment, and belongs to the technical field of site power supply safety control and business collaborative management. The method comprises the following steps: collecting electrical data of intelligent circuit breakers and power supply service equipment, and obtaining corresponding order fulfillment states; establishing a mapping relationship among circuit breakers, branches and power supply service equipment, mapping orders to power supply paths and determining power consumption working condition stages; determining fault types, recoverable levels and automatic recovery safety signs when tripping or abnormal fluctuation occurs; performing shutdown interlocking and path current safety checking when there is running load in the affected power supply path; performing time-delay reclosing or remote resetting for the path meeting the conditions, and generating a recovery load envelope, and gradually unfreezing the frozen orders according to the recovery load envelope; and rolling back to locking and triggering manual resetting approval in an abnormal state. The method can take into account power consumption safety, fault self-healing and order fulfillment continuity.
