Operating procedures for the maintenance and repair of hotel guest room facilities and equipment, and emergency measures for facilities and equipment that often occur.

1. Quickly limit the development of accidents, eliminate the root causes of accidents, remove the threat to people and equipment, and ensure the normal operation of other equipment; 2. Restore the power supply to the power outage users as soon as possible; 3. If it poses a threat to people and equipment, it should be removed immediately, and the equipment should be stopped immediately if necessary. If it does not pose a threat to people and equipment, we should try our best to maintain or restore the normal operation of the equipment, and pay special attention to isolate the equipment that is not directly damaged to ensure its normal operation. Second, the general steps of accident treatment 1. Record the accident time, lights, card drop and related loads in detail; 2. Report to the competent leaders and departments; 3. Determine the nature of the accident and handle the accident according to the plan; 4. According to the inspection and test, according to the scheduling instructions to restore power; 5. Record the accident handling in detail. Three. Outline of various accident treatment schemes 1. Treatment Plan for Casualty Accident 1. 1 Personal Electric Shock Accident According to the operation mode, the operator should be isolated from the live equipment (including primary and secondary equipment) with minimum power failure, and emergency measures such as on-site cardiopulmonary resuscitation and mouth-to-mouth artificial respiration should be taken at the same time. 1.2 Emergency ventilation and exhaust for personnel poisoning, to ensure smooth air, and to isolate the poisoned personnel from the poison source on the premise that rescuers properly protect themselves. In case of food poisoning, pay attention to take suspicious food for testing. 1.3 accidents in which people are hit by objects should be handled correctly at the scene in strict accordance with the principle of emergency, and call for help immediately. 1.4 attention to falling accidents: all the above accident plans must first ensure the safety of rescuers. During the rescue process, call for help to 120 in time and report to the superior. 2. Power grid accident handling plan 3. 1 Misoperation accidents Misoperation accidents may cause casualties, equipment accidents and power grid accidents, and should be handled according to the situation. If the misoperation has not caused any casualties, it is necessary to immediately notify the main control room to inform the clear man-made fault point, so that the personnel on duty can quickly resume operation; If there are casualties, the main control room should send people to check the scene as soon as possible according to the protection action number and the work arrangement at that time, and start the electric shock accident treatment plan for rescue. When a power grid accident occurs, it should report the situation and dispatch quickly, and handle the accident according to the instructions. 2.2 The main power supply of the whole station is out of power (at this time, the accident treatment scheme after communication interruption should also be considered, and it should be handled according to the relevant provisions of the dispatching regulations. 2.3 Busbars of all voltage levels are completely stopped. 2.4 One trip of power supply incoming line running in parallel with two circuits. 2.5 Resonance causes the voltage of substation with bus to suddenly rise or fall sharply. 3.6 bus fault. First of all, according to the protection action, it is judged whether the bus differential action or the transformer backup protection action trips. Then carefully check whether the equipment belonging to the bus (including supporting insulators and bus PT) has traces such as flashover or foreign objects. According to whether the bus can be put into operation in a short time, the recovery process after isolation from the operating system is considered. 2.7 Line grounding fault, such as single-phase grounding or non-phase grounding of medium and low voltage transmission lines (systems), system grounding with neutral point not directly grounded, etc. , mainly focusing on the control of grounding time and the search of grounding point. 3.8 Fault-safety actions correctly judge the fault circuit, and notify the corresponding dispatcher of the primary and secondary anomalies, waiting for the dispatcher to recover. 2.9 busbar voltage loss caused by line fault tripping 2. 10 low-frequency and low-voltage load shedding device actions correctly report load shedding and action rounds. Focus on checking whether the air cooling circuit and DC circuit of strong oil circulation are normal. When the load is not large and the temperature is not high, exit the main transformer linking piece first and use the low-voltage standby circuit at the checkpoint. The rest of the scheduling instructions. 3. Equipment accident treatment scheme 3. 1 Accident treatment scheme when transformer is abnormal 3. 1. 1 Emergency shutdown of main transformer shall be implemented according to the nine requirements of the Provincial Company's Transformer Management Regulations. 3. 1.2 transformer overload 3. 1.3 transformer protection action (light and heavy gas action, differential protection action, overcurrent and zero sequence protection action, etc. ) 3. 1.4 The cooling system stops completely and the temperature of the main transformer is abnormal 3. 1.5 The on-load voltage regulating mechanism of the main transformer is faulty 3. 1.6 The main transformer is seriously leaking oil and the oil level is abnormal 3. 1.7 The connecting parts of the main transformer are seriously heated 3. 1.8. 10 False oil level of main transformer and oil leakage of oil storage tank 3.1.1Two main transformers are running in parallel 3.2 Accident treatment scheme when one switchgear is abnormal 3.2. 1 Circuit breaker mechanism (treatment in case of abnormality) is carried out according to the type of mechanism, such as air leakage, pressure relief and hydraulic mechanism relief.
