Abstract
The utility model relates to a protective bracket for the overhaul of high-voltage disconnectors, which belongs to the technical field of power supply overhaul. The utility model has the technical scheme that the protective bracket comprises a base (1) and a protective rod (2), the base is provided with a protective rod hole, in which the protective rod is inserted, the base and the protective rod are firmly connected, the protective rod is provided with a safety belt-hanging point (4), and the tip of the protective rod is provided with a hook (5). Due to the adoption of the protective bracket, so that the practice of using an insulator as a safety belt-fixing point can be thoroughly abandoned, consequently, potential safety hazards are eliminated, and the occurrence of accidents is prevented; and the protective bracket is characterized by simple structure, good effect, low construction cost and the like and is easy to implement, a great deal of fund can be saved, and the protective bracket can be popularized on a large scale.
Description
Technical field:
The utility model relates to a kind of high voltage isolator maintenance protective stent, belongs to power supply service technique field.
Background technology
At present, when carrying out regular maintenance, the turnover job of 35kV and above disconnecting link, according to security regulations, the disconnecting link maintenance belongs to high-rise working, must adopt the fall arrest measure, traditional fall arrest measure mainly contains and sets up scaffold, uses high-altitude operation vehicle, hoistable platform or take other to prevent the measure of falling.Through field practice, these methods often are subjected to the restriction of operating time and work-yard and can't carry out, thereby more often are to adopt the method that hangs safety belt to carry out the disconnecting link service work." hook of safety belt or rope should be on solid firm frameworks, or aim on the steel wire rope that safety belt uses, and should adopt high mode of hanging low usefulness for " State Grid Corporation of China's electric power safety working regulation (power transformation part) " 15.1.8 bar regulation.Forbid hanging on mobile or the unstable object, as isolating switch (disconnecting link) supporting insulator, CVT insulator, bus post insulator, lightning arrester post insulator etc.But in real work, part model (as the GW5 type) disconnecting link is owing to the design and construction reason, there is not safety belt hanging point up to specification, and adopt traditional method is not that to waste time and energy be exactly breach of security regulation, often is difficult to fully guarantee that at operation field everything goes well with your work carries out and operating personnel's personal safety.
The utility model content
The utility model purpose provides a kind of high voltage isolator maintenance protective stent, and is easy to carry, installs simply, safe and reliable, solves the problems referred to above that background technology exists.
The technical solution of the utility model is: high voltage isolator maintenance protective stent, comprise pedestal and fender rod, and pedestal is provided with the fender rod jack, and fender rod is inserted in the fender rod jack, and is fixedly connected between pedestal and the fender rod, and fender rod is provided with the safety belt hanging point.
Top at fender rod is provided with hook.
The fender rod that fender rod is made for the insulation material, fender rod and fender rod jack matched in clearance, and be provided with pin, fixed protection bar and fender rod jack.Earlier pedestal is fixed on the channel-section steel during use, fender rod is inserted in the pedestal jack again, the bottom is fixed with pin, and the hanging point that at last safety belt is articulated on the fender rod can carry out work, and is easy to carry, installs simple, safe and reliable.
The fender rod jack is arranged on the position of departing from the pedestal center, and the benefit of doing like this is to prevent effectively that the waling stripe of insulating bar and disconnecting link from touching.
The beneficial effects of the utility model:
1. applied widely, through statistical analysis, two perforate distances of base-plates surface are decided to be 250mm-400mm to existing framework, the long 200mm of screw is to guarantee its versatility (on probation through the scene, 80--160 channel-section steel base crossbeam all can use); It singly can not be used for the disconnecting link maintenance, and the maintenance of part instrument transformer also can be used.2. simple installation, the holding screw top design has small embossment, cooperates with hole on the pedestal, can guarantee that holding screw can not rotate; Clamp nut adopts exempts from the instrument design, and hand is twisted can reach fastening effect; Can overhaul adjacent two-phase disconnecting link after installing, staff's activity freely.3. the set-up time lacks, and through on-the-spot test, 1-2 people can install in 4 minutes, and pedestal bottom securing member adopts " groove one hole " design, the hidden danger of not only having saved the set-up time but also eliminated the part accidental falling; Compare conventional method and save time more than 90%, significantly improved efficiency; Effect is especially obvious under the situation short at interruption duration, that workload is big.4. volume is little, and weight is about about 5 kilograms, has only 1% of traditional inspection platform weight, is easy to carry and loads and unloads, and need not to dispose separately haulage vehicle and crane, has not only alleviated labour intensity but also saved job costs.5. simple in structurely be convenient to make and with low cost, easy to utilize.
Adopt the utility model, can thoroughly abandon, eliminate safe hidden trouble the way of insulator as belt anchorage point, avoid accident to take place, the utlity model has simple in structure, characteristics such as be easy to realize, respond well, and the cost cost is low, can save substantial contribution, suitable popularization on a large scale.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Among the figure: pedestal 1, fender rod 2, safety belt hanging point 4, hook 5.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
High voltage isolator maintenance protective stent comprises pedestal 1 and fender rod 2, and pedestal is provided with the fender rod jack, and fender rod is inserted in the fender rod jack, and is fixedly connected between pedestal and the fender rod, and fender rod is provided with safety belt hanging point 4.Be provided with hook 5 on the top of fender rod.The fender rod that fender rod is made for the insulation material, fender rod and fender rod jack matched in clearance, and be provided with pin, fixed protection bar and fender rod jack.Earlier pedestal is fixed on the channel-section steel during use, fender rod is inserted in the pedestal jack again, the bottom is fixed with pin, and the hanging point that at last safety belt is articulated on the fender rod can carry out work, and is easy to carry, installs simple, safe and reliable.The fender rod jack is arranged on the position of departing from the pedestal center, and the benefit of doing like this is to prevent effectively that the waling stripe of insulating bar and disconnecting link from touching.
