The key points of the review include: the reason for using the generator, the list of electrical equipment and the size of its load, the construction position of the generator power supply, the location layout of the generator, the route layout, etc.
1、 This guideline is mainly applicable to those who do not use temporary power on the construction site or the power capacity provided by the owner is insufficient and need to use generators for power supply.
The acceptance contents shall include the generator certificate or inspection report, whether the specifications and models of the mobilized generator are consistent with those in the application, the layout of the generator feeder distribution system, etc.
The generator usage record shall be attached to the progress declaration form and submitted, and the generator power used by each unit shall be deducted from the current progress payment..
The diesel delivery must be witnessed by more than two supervising engineers and signed on the account.
The rated power of the generator shall match the actual load and shall not be greater than twice the actual maximum load.
2.
The generator used on site must have a legal and valid certificate or inspection report, and can be put into use only after being accepted by the supervising engineer.
In principle, the power supply radius of the generator shall not exceed 250m.
2.
When the generator needs to be used, the startup and shutdown must be approved by the supervising engineer before operation, and the generator use record shall be logged in in real time (see attached Table II).
The engineering department shall establish the generator entry and exit account (see attached table I).
When reviewing the use of the generator, the supervising engineer shall recheck whether the generator matches the load, inspect the use of the generator, and the phenomenon of “big horse pulling small car” is strictly prohibited.
4.
3.
The engineering department shall establish the generator diesel delivery account (see attached table III).
4、 Generator entrance and exit management and equipment management 1.
2、 The engineering department shall assign professional supervision engineers to be responsible for the management of generators: the establishment of generator mobilization and demobilization management account, generator mobilization acceptance, generator use records, etc., and clarify the organizational structure and post responsibilities.
The engineering department shall review the size and nature of the power load of the generator according to the requirements of the contract and the construction scheme.
Each generator must be equipped with an electricity meter and fill in the generator use record in time.
Construction generator management guideline in order to strengthen the management of generator use on the construction site, this management guideline is formulated in combination with the actual situation of the group company for reference.
If the generator needs to be used with the mains power at the same time, the mains power interlocking device must be set, and parallel operation with the mains power is strictly prohibited.
Before using the generator on the project site, the user shall put forward the application and power consumption scheme.
2.
The generator shall be set far away from the living area, and the outlet of the generator smoke exhaust pipe shall be set outdoors.
5.
5、 Generator cost management 1.
During the construction of pile foundation, the corresponding quantities of pile foundation using generator and mains power shall be specified, the respective construction scope shall be specified, and relevant records shall be made.
When signing the generator use contract (entrustment) with the generator provider, it is necessary to clarify the calculation method and measurement method of generator cost, and agree on the liability for breach of contract for over reporting and false reporting (for example, the engineering department shall be notified when the generator is started and shut down, and if it is not notified in time, it shall be punished according to the agreement), It shall be confirmed by both parties in writing as the basis for settlement.

4.
3.
The low-voltage generator shall adopt three-phase four wire system for power supply and TN-S neutral protection.
All generators must log in the generator entry and exit account, and indicate the generator specification, model, entry and exit time, use position and use unit.
3、 Application and approval management of generator use 1.
7.
The diesel oil received by the user must be injected into the oil tank of the generator set under the witness of the supervising engineer.
It is suggested to use the method of “lease fee + actual diesel consumption fee” to calculate the generator cost, and the diesel price should be calculated according to the floating market price.
